Facteur de grossissement

Je suis à l'étape finale de mon magasinage pour mon scope.
Je veux pouvoir tirer à 1km quand ça se présentera comme opportunité. Je prévois tirer plus souvent à des distances plus proches, mais mon but est la précision.

Mon arme est une remington 700 5r en .308.

Les scopes que je convoite sont:
- Sig Sauer Tango4 6-24x50
- Bushnell Tactical LRS 6-24x50
et si je trouve rien en stock:
- Vortex Viper PST Gen II FFP

Comme le titre l'indique, mes choix ont tous pour des scopes avec 24x de grossissement ou proche. Par contre, j'aurais plus de choix pour des 14x ou 16x, donc: Pour les distances plus éloignés, disons passé 600m, est-ce qu'on voit les impactes encore assez à 14 ou 16x?

Edit: Sig Sauer risque de ne plus être une option puisque les distributeurs n'en ont plus en stock et attendent la fin du ShotShow pour rouler leurs nouveaux produits. Il y aura également une hausse de prix.

Non

1 click,
J'arrive pas à trouver. Le Sniper Canadien qui a tiré à 3.540 m, c'était quoi son scope ? Il me semble un 10 X seulement ???

Pour tirer à la cible à plus 600 verges, mon opinion c'est au moins 24 X.

C'est bien ce que je pensais. Je crois que je vais me ramasser avec un Bushnell. Domage que les nouveaux modèles soit pas plus que 16x ou à 2000$. Y sont beau.
Les vieux oldschool font la job j'imagine.

Je n'ai pas trouvé la lunette, seulement l'arme et la munition. C'est un gars du JTF2.

La mémoire est revenu, j'ai lu dans un cataloge Leupold je crois que le télescope est celui-ci avec TMR:

https://www.leupold.com/scopes/rifle-scopes/mark-4-lr-t-3-5-10x40mm

Ça c'était Rob Furlong lors du tir à 2 430 m.

Non, Rob Furlong avait celui-ci avec Mil Dot:

https://www.leupold.com/scopes/rifle-scopes/mark-4-lr-t-16x40mm

MacMillan Tac-50 coiffé d'un Leupold Mark 4-16x40mm LR/T M1

Je ne crois pas que le JTF2 utilise une lunette Leupold Mark 4-16X ni une Leupold Mark 4 LR/T 3.5-10x

Faut que je trouve ou j'ai vu ça pour le 3.5-10 x 40mm!

#Expert Analysis

The Canadian snipers had carefully chosen their hide site. From an elevated position, the Special Operations sniper looked through his scope at a stationary human target leaning against a cement wall over two miles away. The four-man sniper team had been pushing their shots out further and further into Mosul over the course of several days, taking down ISIS terrorists in long-range engagements. Now, they were about to make history.

Three Canadian sniper detachments have been active in Mosul, Iraq. Two of those sniper detachments hail from Canadian Special Operations Regiment (CSOR) and one from Joint Task Force 2 (JTF2), both units falling under Canadian Special Operations Forces Command (CANSOFCOM). CSOR handles tasks commonly associated with American units such as Special Forces and Rangers while JTF2 is Canada’s counter-terrorism unit, filling a role similar to Delta Force. That CSOR is in Kurdistan conducting an advise and assist mission is public knowledge. JTF2 was accidentally exposed in theater by a video released in 2015. What the Trudeau administration doesn’t want people to know is that Canadian troops are actively involved in combat. Like many other western governments, the advise and assist mission is used as a politically neutral term to disguise what is really happening on the ground.

The record-breaking shot was taken by the JTF2 sniper team nearly a month ago, but is just being publicized now, largely because the Canadian military is proud of what their men have accomplished despite what hand wringing politicians might think. Let’s get one thing straight, the record-breaking shot was not at a distance of 3,450 meters as the press has reported, but 90 meters further at a range of 3,540 meters. This smashes the previous record-setting distance for a sniper kill which was 2,475 meters held by British sniper Craig Harrison.

Canadian snipers are known to be amongst the best in the world and the JTF2 sniper detachment had been training for ultra-long range engagements prior to their deployment in preparation for Mosul. From their sniper hide, a number of factors lined up making the record-breaking shot possible. Using Kestral wind meters and ballistic software, the guess-work has been removed from ballistics. This truly makes sniping a science, as successful shots are based on math. On this particular day, there was little wind and no mirage. Through their scope, the sniper and spotter saw the target remaining still long enough for them to hit from 3,540 meters away.

The McMillan Tac-50 was hardly a new rifle, but would do the job. The round fired was a match grade armor-piercing incendiary (API) round. JTF2 mostly utilizes Schmidt and Bender scopes, but also some made by Night Force. Which optic used that day remains unknown at this time. The rifle had been customized in order to gain the mil elevation needed to reach a target at such great distances by attaching special rails to the weapon. The adjustments dialed into the scope by the JTF2 sniper were 113 mils of elevation and 6.5 mils of windage. To learn more about the mil-dot system and how snipers use it to adjust for distance and wind, take a look at the following website.

The JTF2 sniper fired, and the target went down, felled by a .50 caliber bullet from over two miles away. The episode was actually recorded by a Predator drone circling overhead. SOFREP has also seen confirmation of the shot from CANSOFCOM.

Minutes later, the same sniper/spotter team noticed a group of three ISIS terrorists standing close to each other at about 3,200 meters away. It would have been another record-breaking shot. The sniper fired at the group and all three hit the ground. One shot, three kills? Unfortunately not this time, the three terrorists sprung up and ran away. The bullet most likely passed right in between them. For the Canadian hunter/killer team it was still an amazing day. Chalking up a record-breaking sniper kill is one thing, having video evidence of it puts the shot into a whole other league.

The JTF2 snipers cannot be named for security purposes.

Explique pourquoi svp.

Tu n'as qu'à lire le texte posté par Ktmrider.

...the JTF2 sniper detachment had been training for ultra-long range engagements prior to their deployment in preparation for Mosul.

Ces lunettes ne conviennent pas pour ce genre de mission.

J'crois comprendre 1 click mais Furlong, il a fait comment ?

Il faut demander ça à Furlong et non à moi.

Craig Harrison a utilisé un Accuracy International  L115A3 en calibre .338 LM pour battre le record de Furlong, il avait une lunette  SB 5-25x56 PM II LP. Lui son tir était limite pour le calibre et pourtant il a réussi 2 475 m. Pas mal pour du .338 LM. Il avait la densité de son coté.

Exact, le tir de Chris Kyle de 1.9 KM à une altitude plus basse avec une 338 était pas mal la limite!

Le JTF2 qui détient le record avait un Schmidt Bender PM II 5-25x56 mais aucune idée du model exactement. Sûrement rien de moins que le top of the line lol
Un de ceux là probablement dans le tan
