BFR 45-70

[coloradoyaler]

Hello

I am looking for info and results. What is the max velocity for a 350gr Hornady bullet out of a 7.5 barrel bfr? Also, what is the max velocity of a 460gr Cast Performance bullet out of the 7.5 barrel?

Thanks
Mark

Mine came with paperwork that said the BFR could take Marlin/Ruger #1 loads. I personally wouldnt want to pull the trigger on those.

Other than that, standard pressure loads equal 454 Casull loads with much less recoil and is a tack driver.

these numbers are with a 10" barrel in the BFR,
350gr hornady FP interlocks,
velocities averaged over 5 shots.
(in a 7.5 inch barrel, you may get 50fps lower velocities??)

powder: SR4759
27gr 1256fps
28gr 1303
29gr 1342
30gr 1401
31gr 1440
32gr 1535


powder: IMR4198
32.0gr 1219
34.7gr 1347
37.3gr 1431
40.0gr 1573
42.7gr 1659 (beginning to get painful)
45.0gr 1685 (yeah.... it gets painful above this point)

i have settled on 31gr SR4759 or 37.3gr IMR4198.

when i load thge powder, i then take take a cut piece of toilet paper that i ahve cut into 9 pieces and stuff one piece down onto the powder.
this keeps the powder up against the primer. cheaper than using filler material.

i have since then had jack huntington shorten the barrel to 8+3/8 inches
