I want to build a >40" barreled flintlock in .58 or larger caliber (looking heavily at .62), round ball only, for hunting whitetails and feral hogs inside 80 yards. As always, thanks for what I have already learned from the forum. Shooting round ball, and shooting over .50 caliber, are both new to me. I'm currently looking at Jim Chambers' Virginia Rifle kit, and I am open to others.
Questions:
I would like to find an accurate load in the 950-1150fps muzzle velocity range. Should large PRB shoot well in that range out of a 1-66" twist? Any better twist recommendations?
In your opinion, and assuming the rifle is designed well, how large can I go in caliber before recoil becomes excessive? I would like my normal load to compare to a 3" mag. 12ga shell, and a peppy load (1200+ fps) to be just under .300 Win mag. territory.
