Have had my good old Lyman GPR caliber 50 Cap lock for over 20 years now. Built her from a kit purchased at Sportsmans Warehouse.
(that location is now a big chain church of some type, and where the gun counter was is now an alter)
My mentor, a guy named Niki or Nicky worked the counters back there, and he set me up with the kit, and all the basic supplies and accessories i needed to succeed. Back then the kit cost between 250-300$ if I recall correctly.
The store didnt sell real black powder, but had plenty of BP subsitutes. So 777, Pyrodex, and Jim Shockeys are 3 types ive used over the years. Ive settled on 777 in FFF.
Nicky said FF might not ignite as good, so just use FFF and should be fine. I was in no position to contest, so FFF has been what i go for, no questions asked....(feel free to comment)
I use between 70 and 90 grains of 777 FFF under .490 round ball patched with .015 bore butter lubed patches. Greatest accuracy comes with 70 grains, where im of the assumption that 90 grains is probably better than 70-80gr for deer hunting, and groupings only open up ever so slightly with the extra powder. This is just what i was taught/told, and it has worked at killing deer (4 deer in about 20 years, 5 shots fired...one was a total miss, didnt even graze him)
Say 3" at 50 yds with 90grn bench rested rather than 2.5" with 70 grns.
Anybody have any clue what kind of velocities this is creating? Where is the envelope in this situation? Ive started getting worse groups, and torn up patches around 95grn or above, so thats where I quit and backed down.
