- Selon le livre hornady 8 th edition les loads min et max de imr 4198 pour les marlin 1895 sont: 40.5 gns et 47.9 gns mais y a une particularité importante avec ses boulets (325 ftx) faut ABSOLUMENT TRIMER LES DOUILLES A 2.040 due a l'ogive plus longue du ftx.
Bon reload!!!
Affirmatif: il faut recouper les douilles @ 2.040" si tu veux charger les balles FTX de 325 gr (#45015).
Après la recoupe de la douille @ 2.040", Hornady spécifie une longueur hors-tout de la munition avec la balle FTX de 2.590"
Dans le futur il te faudra effectivement tenir deux sortes de douilles.
je ne suis pas parfait en anglais mais ci je traduis se texte sa me dit qu'il y a seulement trois model de carabine que l'on doit couper les douille
( original Winchester Model 1886 Miroku Winchesters and Browning Model 1886s ) mais je vais quand même faire des teste
Notes From the Lab:
.45-70 Government 1895 Marlin
The .45-70 Government started life as a military round in the Model 1873 (Trapdoor) Springfield
rifle before becoming popular with civilians using single-shot and lever-action rifles. Today it remains
popular among black powder cartridge shooters, but its greatest success is as a hunting cartridge in
lever-action rifles such as the Winchester Model 1886 and Marlin Model 1895.
Many of the loads listed still have “space” between the base of the bullet and the powder.
When used in lever-action rifles with tubular magazines, it becomes important to place a heavy crimp on
the case/bullet to prevent bullets from being “deep seated” when subjected to inertia associated with
recoil.
When loading the Hornady 325-grain FTX bullet, cases were trimmed to 2.040 inches for a
Cartridge Over All Length (COAL) of 2.590 inches. However, in separate tests, FTX bullets were seated to
the crimp cannelure in cases measuring 2.100 inches (industry specifications) and fed reliably in several
Marlin rifles, but failed to feed in two of them. In trying this load in an original Winchester Model 1886
and both Miroku Brownings and Winchester Model 1886s, function was flawless.
It has been observed that when using the Hornady 350-grain FP bullet seated to its crimp
cannelure with a COAL of 2.545 inches, Miroku Winchesters and Browning Model 1886s will not allow it
to chamber due to their short throats. The Ruger No. 1 and Miroku Winchester Model 1885 will likewise
not accept this load without lengthening the throat.
