Chuckpa yep 25 grains of fff, # 15 pach and your set to take them squirrels right out of the trees at 30 yards.
chuckpa,
.015 patch is what I use also. However,I have used .32cal
Buffalo Bullet Ball-ets with at least the same,if not better than
the PRB,results.Ball-ets do not require a patch.i.e. powder,
ball-et and you are loaded.Great when squirrel hunting.
