It is easily done and surpassed.

Reloader #7



My load is as follows 420 hard cast perfromance Gas check

51 grains of Reloder 7

Starline brass

Rem 9 1/2 LR Primer

seated to 2.50 OAL.



This brings a consistent 2125 fps in my marlin 1895 Cowboy

HOWEVER RECOIL IS ROUGH

*I would HIGHLY recommend you start with a lower charge and SLOWLY work up to 51 grains.

Make sure you and your rifle can handle it.

Good luck

I have only used the Alaska Bullet works 405grs bullets and 350 grs North fork over a proper amount of vv-n-133.

The 350 Bonded NF outpenetrates everything I have tried in 45-70 and is my only hunting load for the 45-70. You can reach about 1900f/s in a 22" barrel without exessive pressure.

I have pressure tested mine using a Oehler 43p. The 1900f/s load has average pressure in the 37-38 000psi range. I have seen 40k + in 450M and 444 so I guess it's safe enough

In my 1886 EL I use WW brass, WLR primer, 47 Gr. H4198 under a Rem. 405 Gr. Bullet for about 1875-1900 fps.
I use 44.5 Gr. H4198 under an Alaska Bullet Works 405 Gr. bonded bullet for 1825 fps. With my Lyman receiver sight and AO front post I do about 2 inch groups from the bench.

Thanks for the info guys.

I think it is funny though that I do have some IMR 4198 but every one so far uses H 4198.

I learned with my 458 win and 600 grain barnes bullets, that the two powders are not identical.
