Walker load advice
I have a ASM Walker and have been shooting 50gns. of Pyrodex fffg with round ball. I fired a few cylinders with 60gns with no problem other than the loading lever dropping down a couple times.My question is,a friend gave me 2 lbs.of GOEX ffg black powder can I still load 50gns and would 60gns still be OK? I thank all for any input.
