T7 FFG over Pyrodex

[fla shooter]

Have been shooting 100 GR. of Pyrodex P. Just picked up some T7 FFG to try out. Should I back down to about 90 GR. of T7 to equal 100 Gr. of Pyrodex

I think i would just try it at 100 and see how it groups, if it does fine i would stay with the little more velocity , it really would matter to me to be honest

Since you changed powder you might have to experiment but not much. Try 90 grains and see what happens. Good luck with the powder change and be sure to swab between shots when shooting T-7.

I've been using a 90 gr. charge of T7 2F for about 5-6 years now and it's more than enough to get the job done.
