Home Forums Hunting & Shooting BPCR 50-70 Govt Granddaddy of them all for sport or battle

Absolutely, the 80 extra grains of momentum at 1250 fps for the 530-grainer is quite the Quantum of Solace for the bizon hunter.
That will shake your martini instead of stirring it.
That bullet is licensed to kill.
Enough of the James Bond jokes.

I have a short and squat 535-grainer I could get to work with BP in a .510"-grooved 1:24" twist Rolling Block with gunner500's recipe.
.50-70 rifles, I have 4 shooters to try various bullets:

1. U.S. Springfield 1866 Trapdoor: Marked "1864" on the lock plate from percussion conversion by "second Allin alteration," marked "1866" on breechblock.
About 29" barrel bore, about 32" including breechblock.
Lined barrel, .515"-groove, .500" bore, 3-grooved, 1:42" twist.
It must be a carbine or cadet rifle being that short.
8 lbs 9 oz including brass tacks and human hair wind gauge.
I do not think the Bubba that decorated it with brass tacks bobbed the barrel. Crown and front sight look unmolested.
A master gunsmith overhauled, cleanedand lubed it and repaired a crack in the stock with epoxy and brass pins,
before I tied it to a tire and pulled the trigger with a string. 450-ish-grainer and 70 grains of FFg GOEX was proof enough for me.





2. McNelly Carbine replica (Cimarron/Chiappa/A.C. Armisport) of Sharps 1859 percussion converted to centerfire a la Texas Rangers.
22" barrel, 1:18" twist, .512" groove, 6-groove, .504" bore, 8 lbs 0 oz.



3. 1874 Sharps replica "Long Range Target Rifle" (Pedersoli)
34" barrel, 1:26" twist, .512" groove, 6-groove, .504" bore, 11 lbs 12 oz.

4. Remington Rolling Block replica "Buffalo Model No. 2" (Pedersoli) re-barreled with Oregon Barrel Company tapered octagon and custom sights
28" barrel, 1:24" twist, .510" groove, 6-groove, .498" bore, 9 lbs 13 oz.
