Will soon have a Magnum Research BFR in 45-70 in my greedy little paws
This is the 7.5 in. version. Apparently the biggest drawback using factory ammo and most handloads is a lot of unburnt powder, even find this with my 18.5 in. Guide Gun.
I plan to start out with Trail Boss loads, has a fast burn rate and low recoil
Does anyone have experience loading more powerful loads that would suit this short barrelled hand cannon? I cast my own bullets, from Lee 340 gr.'s to 560 gr. WFNGC T-Rex killers. I was looking at 460 S&W data and wondered if the powders and loads suitable for that huge case might not be a place to start. The BFR is available in 460 S&W so pressures in the larger 45-70 case shouldn't be a concern. I've been handloading for 20+ years so I know the risks of messing in uncharted waters, just wondering if someone has got their feet wet before me
Thanks,
Sharpset
