Ithem!

.243 aussi peut etre tres bon!! calibre tres tres precis.

.223

Mon 2ème choix irait vers la 243.

C'est comme demander ... un gm, un ford, dodge ou toytoy ??? Je crois que sa depend plus de toi que d'autre chose. Moi j'ai une 22-250. Je suis rendu a 2000 coups et elle tire encor tres bien. Si tu est un gars presser qui n,aime pas attendre entre chaque balle je crois que ce n'est pas une bonne idee d'aller vers les wildcat comme 22-250 et 243. Si tu est pas presser et que tu veut faire du 300, 400 verge la c,est calibre sont tout designer contrairement au 204 qui est un peu leger pour le long range SELON MOI. Ce nest que mon opinion personnel donc a toi de determiner tes besoin.

243-223... j'aime la 243 car avec un gros canon et un twist pas trop rapide, tu peux tirer une grande variete de boulets et de poid... donc des heures de plaisir...

1 - 223 Rem ( tir de précision / vermine )
2 - 243 Win ( tire de précision / chasse / vermine )
3 - 204 Ruger ( vermine )

Mon choix personnel : 243 Win car plus polyvalent

Merci les gars je vais penser à vos sages conseils.

223 moi aussi jadore se calibre pis au prix que sa coute tes meme pas oubliger d,avoir une 22 lolll

Ce qui me fait peur avec la .223 c'est que l'on commence à dire que les calibres militaires (.223 .308) ne seront plus exportés des USA.

J'ai toujours dit que les meilleurs BC étaient dans les calibres 6mm à 6.5 mm dans les small bore. Alors tu parles de tir à la cible et je ne connais pas la distance maxi que tu veux tirer. En supposant que tu veux faire du long range... le meilleur calibre que tu as énuméré et qui a le meilleur coéficient balistique , le 243 (6mm) est le champion dans les 3 calibres que tu mentionnes.

J'aimerais bien savoir si ces chiffres sont exacts car je m'enlignais sur une Rem 700 SPS .243

Dante m'a déconseillé le 22-250 pour la même raison.

oui s est comme la 6.5x285
au international de cannaught j ai discuter avec le quebecois qui tirait ce calibre et il le changeait tout les 8 a 900 coups ouffffs

High-Velocity 6mm for Long-Range, Varminting, and Tactical Use

.243 Win--Multi-Purpose Precision
If you could have just one rifle to slay varmints, hunt white-tails, shoot paper at long range, and duel in tactical matches, it would be hard to beat the .243 Winchester. This versatile "little brother" of the .308 Winchester is a true triple-threat as a match cartridge, varmint cartridge, and game cartridge. With 115gr DTAC bullets, a .243 rivals a 6.5-284 ballistically out to 1000 yards. Shooting 80-100 grain hunting bullets, a .243 will anchor a buck with authority. Driving the light 55-75 grain pills, the .243 provides the flat trajectory and high impact energy varminters love. As a tactical round, the .243 is one of the best, offering excellent ballistics, moderate recoil, and stone-reliable feeding from a detachable magazine.

Source for Name-Brand Factory .243 Win Ammo: LuckyGunner.com



The .243 Win excels with a wide variety of powders, and excellent factory-loaded hunting ammunition is available. Off-the-shelf .243 rifles from Howa, Remington, Savage, and Tikka perform admirably with little or no modification. The "improved" version of the cartridge, the .243 Ackley, can do everything its parent can do, with more velocity, and greater brass stability thanks to its 40° shoulder. Among the Ackley variants, the .243 AI is rightly one of the most popular. It is easy to fire-form, and commercial dies are readily available. Barrel life is the downside of both the .243 AI and standard .243. These chamberings pump a lot of powder through a small bore. The result, typically, is rather short barrel life, sometimes less than 1500 rounds. A few folks have been experimenting with the use of very slow, cooler-burning powders. There is some evidence that the use of super-slow powders, combined with modified cleaning regimens, can result in significantly enhanced barrel life.


Brass--An Abundance of Good Choices
.243 Win shooters are fortunate as Lapua, Norma, and Winchester all make good brass for this caliber. We've shot all three brands. The Lapua and Norma both yielded excellent accuracy, and both brands were very consistent weight-wise. The primer pockets did stay tight a bit longer with the Lapua, and the neck tension stayed more constant after repeated firings. Since Lapua .243 brass is usually less expensive than Norma, Lapua is our first choice. But if you find some Norma .243 cases at a good price, don't hesitate to buy them. You may have to adjust your load a bit as the Norma we tried had slightly higher H20 capacity than the Lapua brass.

Brass Brand Lapua Norma Remington Winchester
MidwayUSA.com
Price/Part # $49.99/100 #235456 $65.99/100 #292767 $20.99/100 #157973 $9.99/50 #485259

Domestic (Remington and Winchester) brass is significantly less expensive than Lapua or Norma. If you sort the cases by weight and clean up the primer pockets and flash holes, Win brass can shoot very well indeed. Winchester would be our first choice if you need large quantities of brass, or are shooting tactical matches where it's common to loose brass in the weeds. One Midway user observed, however: "[I prefer] Remington brass over Winchester, due to the different internal volume of the brass. Since the internal volume of Remington is smaller I seem to get more consistent results from both the chronograph and down-range performance."

Hunting Bullets
For varminters, the Sierra 70gr Blitz-King and Hornady 75gr V-Max offer a good combination of accuracy, BC, and explosive impact on target. The Berger 80gr Varmint bullet is exceptionally accurate but doesn't impact as explosively on target. For coyotes, the 80gr Nosler Ballistic Tip and Hornady 87gr V-Max both buck the wind pretty well and hit hard. For small to medium-sized deer, Sierra recommends its 85gr HPBT GameKing for soft-tissue shots out to 200 yards. Where deep penetration and better weight retention is required, you need bullets like the Nosler 95gr/100gr Partitions, Remington 100gr Core-Lokt? SP, or the Sierra 100gr SPFB Pro-Hunter. Click Here to download Nosler Partition Video (requires QuickTime).

Hunter and outdoor writer Chuck Hawks notes: "When using the .243 to hunt medium-size big game animals, bullet selection is paramount. Rapid (but controlled) expansion is very important, as the small diameter 6mm bullet has little shocking power if it does not expand and expend its energy inside of the animal. Two bullets in the 90-100 grain weight range that have earned a good reputation on medium size big game animals are the Remington Core-Lokt and Nosler Partition."

The Combined Technology 95gr Ballistic Tip (made by Nosler) is another favorite with deer hunters. South Dakotan Grant R reported: "This is a very capable, accurate bullet. I used this bullet last fall deer hunting and was more than amazed at its performance. Shot a mule deer at 512 yards with it, bullet exited, deer ran about 20 steps and that was it."

Forum member Jeffrey H of Mississippi reports: "I have had very good results with the Combined Technology Ballistic Silvertip with the 95gr bullet. My son used them to take 3 deer this year and none walked away. I have also used the Barnes TSX in 85gr and have not only had excellent accuracy from these, but I took two deer using them and had very good kills with both. I guess we all know how accurate the 6mm bullets are."

Mike Daly, Hodgdon's Director of Customer Service, writes: "The 243 quickly gained a reputation for being a great hunting cartridge. When coupled with H4895 and a 55gr Nosler Ballistic Tip, the 243 will deliver over 4050 fps for taking varmints. For larger varmints, the Barnes 85gr Triple Shock" X-BT bullet will deliver great performance with a max load of H4350 driving it over 3200 fps. For deer and antelope hunters, it is hard to beat the Speer 100gr BTSP powered by H4350 at over 2970 fps. For Mule Deer, [I use] a Nosler 95gr Partition bullet driven to approximately 3085 fps by a maximum load of H4350. This combination has accounted for many deer, a few antelope and even a coyote or two."

Match Bullets
With enough powder capacity to drive the 0.585 BC 115gr DTACs at 3150+ fps, the .243 Win is an outstanding long-range cartridge. George Gardner of GA Precision recently won the long-range Shumway Cup segment of the 2006 Snipers' Hide Cup shooting a straight .243 Win. In so doing, George bested Terry Cross (.260 Rem) and David Tubb (6XC), so you can see the .243 is a top performer at long distances. In fact, in terms of Wind Drift, a .243 running 115s at 3150 fps beats both the .260 Rem (2850 fps) and the 6.5-284 (2950 fps) running 142 MatchKings.

In addition to the DTAC 115-grainers, other excellent long-range match bullets include: 105gr Berger VLD, 106gr Clinch River, 105gr Hornady A-Max, 105gr Lapua Scenar, and the 107gr Sierra MatchKing. The 105 Scenars can be incredibly accurate, but their shank diameter is a few ten-thousandths less than the Berger 105s, Hornady 105s, or Sierra 107s, so the Scenars seem to work best in barrels with a fairly tight bore diameter. The Bergers like to be seated well into the lands, while the MatchKings and Scenars work well either jammed or jumped. The 105gr A-Max, with its polymer tip, is a good dual-purpose bullet that works well both for long-range paper-punching and long-range varminting. The A-Max will expand on impact while some high-BC match bullets will make an "ice-pick" wound. Matt Bianchini tells us: "I use the long-range bullets for woodchuck hunting here in PA with great results out of my 243 AI. My favorite is the Hornady 105gr A-Max piped at around 3290 fps by a 27" Shilen. Also had great success on PA whitetails."




Preferred Powders--Match Your Propellant to Bullet Weight
For the heavy bullets, in the 100-115 grain range, modern slow-burning extruded powders produce great accuracy with low ES and SD. With the 105-107 grain match bullets, try H4831sc, Reloader 22, Reloader 25, and Vihtavuori N165. Sierra's recommended Hunting Load for its 100gr soft-point FB and BT bullets is 36.2gr IMR 4064 at 2900 fps. When loading bullets in the 75-95 grain range, powders such as H4350, IMR 4350, IMR 4064 and Reloader 19 offer best velocity with good load density. Many long-range varminters recommend H414 with the 87gr V-Max. For the light varmint 60-75 grain varmint bullets, you can use faster powders, such as Hodgdon Varget, H414, and Vihtavuori N140. For the 70gr BlitzKing, Sierra suggests a load of 38.6 grains N140 at 3200 fps. Maximum velocities with the lighter bullets can be achieved with ball powders such as Winchester 760 and H380. Click Here to download Sierra Bullet's complete .243 Winchester Load Map as a .pdf (Adobe Acrobat) file. With data for two dozen powders, this provides suggested loads for Sierra's entire 6mm bullet line-up from 55 to 107 grains.

.243 Win For Tactical Comps We asked GA Precision's George Gardner why he chose .243 Winchester for his Tactical Comp Gun. He replied, "Why would I run anything else? Think about it. I'm sending a .585 BC 115 at 3150 fps--that'll shoot inside the 6XC and .260 Rem with ease. I'm pretty sure I have found the Holy Grail of Comp Rifles. There are no brass issues like you can get forming .260 brass. I don't have to worry about doughnuts, reaming necks--none of that. And the choice in brass is great too--run Lapua if you want max reloads and great accuracy. Run Winchester if you're on a budget, and so you won't cry if you lose some cases in a match. I can get 10-round mags, and feeding is 100% reliable, since the case is identical to a .308 except for the neck. Accuracy-wise, I don't think I'm giving up anything to the .260 Rem or the 6XC." We then asked George if he'd considered using a .243 AI instead: "Yeah, the cases look cool with that 40° shoulder, but I think the standard .243 feeds a little better. And I don't think I really need the extra performance of an improved case. Run the ballistics for my load--115 moly DTAC at 3150 fps. You've got less windage than a 2950 fps 6.5-284, with cheaper brass, cheaper dies, cheaper bullets, and less recoil."

.243 Ackley Improved--More Velocity, Less Case Stretch
by Bob Blaine, Sinclair International

Parker Ackley reluctantly developed the .243 Ackley Improved ("AI"). Ackley finally gave in to his customers' requests to develop the .243 AI. He had always felt that the .243 Winchester was already an improved configuration, but he did say that the best thing to be gained by improving the .243 Winchester was to substantially reduce the case-stretching problems. The .243 Winchester parent case has always stretched brass, almost as bad as the Swift. Even though you get more velocity with the improved .243, I've also found that the improved version gives a bit more throat life than the parent case does.

The .243 AI delivers more velocity by virtue of enhanced case capacity--roughly five grains more H20 capacity than a standard .243 Winchester. The .243 AI has a water capacity of approximately 57 to 58 grains, compared to 52-53 grains for the standard .243 Winchester.

Fire-Forming
As always, fire-forming is done by one of two methods. Most of you will fire form the brass with loaded .243 Winchester. Ackley always said to use factory loads, or reload equivalent ammo to have a "snappy" load to form the case out properly. You never want to use a reduced load to form with, since you need the pressure to form properly. If your rifle is chambered properly, you should feel a slight amount of resistance as you close the bolt on a new piece of brass. If you do not get this "feel", you may need to seat the bullets out to .010" to .015" into the lands to make sure that the base of the case stays in solid contact with the bolt face. The fire-forming method I have been using more lately employs medium burn-rate pistol powders and Cream of Wheat. I will start by loading about 10 grains of SR4756 or Unique into the case, and then I fill the case up to the body shoulder junction with Cream of Wheat. I will then take a large pinch of polyester filler, which can be found at any fabric supply store, or sewing department, such as at Wal-Mart. I will then take the pinch of polyester and load it into the case so that it fills up the shoulder area of the case effectively making sure that the filler is held securely over the powder for fire-forming. During the fire-forming, I like to dry brush with a nylon bore brush every 10 to 15 rounds. This removes any loose debris from filler that has accumulated. [Editors Note: Do NOT seat a bullet using this "Cream of Wheat" method. You can cap the case with a bit of wax to keep everything in place. However, Bob finds the wax is not necessary if the polyester filler is placed securely.]

Recommended Loads
I'm often asked, "what gunpowder do you recommend"? I generally recommend medium-slow or slow burn-rate powders for the .243 Ackley. I have found, with my rifle, that H414 is pretty much my first choice for use in the .243 AI. H414 tends to give me great accuracy, with good velocity. Saying this, I have tried many other propellants and have found the following powders to be worth looking at for your needs: AA-2700, H414, H4350, VV N150, VV N550, VV N160, VV N560, RL19, H4831sc, and VV N165, to name a few of the powders that I have tested over the years.

Different Reamers, Different "Improveds"
One thing that you need to watch for is what version of the .243 Improved that you have. This depends, for the most part, on whose reamer you will be using for the chambering of your barrel. It is easy to determine if your .243 Improved is the .243 Ackley Improved, or the .243 Winchester Improved. If you have the .243 Ackley Improved, the shoulder-body section will measure .460" dia. at this point. If you have the .243 Winchester Improved, the shoulder-body section will measure .455" diameter at this point. Both cartridges have the 40-degree shoulder. I have used both versions and found that you can use any data developed for either version interchangeably.

The .243 Ackley Improved is one of the best long range varmint rounds going, and can add some extra punch for your light big game rifle as well. One would be hard pressed to ignore a cartridge as versatile as the .243 Ackley Improved.


Matt's Screamin' Yellow Ackley--The Need for Speed


.243 AI Speed Demon
In a long-range varmint rifle, speed kills. Ultra-high velocities deliver flatter trajectories and more explosive hits. And that's where the .243 Ackley really shines. While we don't advocate "pushing the limits" with factory actions, Matt Bianchini has explored the upper limits of .243 Ackley performance with his Farley-actioned long-range rig, fitted with a 29" Lilja 3-groove, 8-twist barrel. Using a stout load of Reloader 25, Matt's "Screamin' Yellow Ackley" has topped 3340 fps with Clinch River 106s. That is serious speed for heavy 6mm bullets. This shows a well-built .243 AI leaves Dashers and 6XCs in the dust when it comes to pure velocity.


Dies and Reloading Gear
Since the .243 Win is such a popular cartridge, all the major die-makers offer reloading dies. It's hard to go wrong with a Redding Type 'S' Full-length bushing die--item 77114 for the standard .243 Win and item 77420 for .234 AI (40?). This will both resize the case (and bump the shoulder) as necessary, and allow you to adjust neck tension with bushings. Alternatively, you can go with a body die (item 75114), and a separate neck bushing die (item 71114).

If you load primarily one brand of bullets, another slick set-up is to buy a Forster full-length .243 sizing die, and then send it off to Forster to have the neck honed for your desired amount of tension. Forster charges just $10 plus shipping for this service. This elegant one-pass sizing solution produces very straight rounds with low run-out. We also believe that doughnuts (in the neck) form less readily if you full-length size with non-bushing dies as opposed to using bushings. Bushing dies leave a little bit of the neck unsized, and that's where the brass can build up.

For bullet seating, both the Redding Competition Seater (item 55114) and the Forster Ultra-Seater (item U00034) work great for the standard .243 Win case. If you shoot a .243 Ackley, Redding's .243 AI Comp Seater (item 55420) costs quite a bit more than the standard version and Forster doesn't list a .243 AI seater in their catalog. However, you can just run your chambering reamer into the inner sleeve of either die to fit the Improved case.

If you want the "Cadillac" of production seater dies for the .243 Win, order the Wilson Stainless Micrometer seater (item 50-1114S) from Sinclair International. Costing only a few dollars more than a Redding Comp seater, this die is a joy to use, providing very positive control over bullet seating depth. When used with a quality arbor press, the Wilson offers unrivaled "feel" for bullet-seating force. This can help you monitor neck tension, one of the most critical factors in maintaining low ES and SD for long-range accuracy.

Great Factory Rifles in .243 Winchester


The Model 700 VLS represents one of the better values in the current Remington Line-up. The VLS offers a matte blued action with 26" heavy barrel (1:9/125" twist) with target crown. The laminated stock includes Monte Carlo cheekpiece, and a wide, flat, beavertail fore-end for stability in front bags. Suggested retail for the Rem 700 VLS is $951.00, with street price around $750.00 in .243 Win.



Long-favored by serious varminters, the Savage 12-BVSS is ready-to-run right out of the box. With a strong, pillar-bedded laminated stock, and fluted 26" heavy barrel in 1:9.25" twist, the single-shot 12-BVSS can often deliver 1/2-MOA groups with tuned handloads and can easily shoot under 1 MOA with factory ammo. The crisp, AccuTrigger" can be adjusted down to about 1.5 pounds, so all you really need is to skim-bed the action and add a scope and you're ready for the varmint fields. MSRP for the 10-pound BVSS is $746.00, with street price under $630.00. NOTE: This rifle is not available in the 2008 Savage product line, so you'll have to look for older inventory.



The Howa 1500 Varminter Supreme is an excellent rifle for the price. You can often find the laminated Howa varminters for under $600.00 (MSRP is $711.00). The Varmint Supreme features a sturdy and very comfortable laminated stock with vent holes for barrel cooling. The action is strong and smooth, and the barrels are probably a bit better, on average, than you'll get from Remington.

WARNING: ALWAYS start 10% below these loads and work up. Pressures can vary dramatically from one barrel to another. Seating depths have a huge effect on case pressures--moving the bullet just .015" one way or another can push a "safe" load into the danger zone. Powder lot variances can be extreme--you may have to adjust a full grain or more. Whenever you buy new powder, even the same brand, start 10% low. NEVER assume pressures will be safe if you change lots or ANY component. Case web growth is probably the most reliable indicator of over-charge. By the time you're getting stiff bolt lift or ejector marks with fresh brass you've exceeded proper pressure levels. Ambient temperatures can alter pressures considerably. Don't assume cold weather loads are safe in summer. As you approach max loads, reduce the load increments. Just 0.2 grains can make a difference.
