Im going to pick up a box of 245 grain buffalo ballets and a box of 223 grain power belts and give them both a try a 50 and 100 yards. I dont plan on shooting the flintlock at anything over 100 yards. I only do that with the inline and only if i can find a nice steady tree branch.. I got lucky last year with those 2 deer i hit off hand. Great clean kills though! I think 90 grains with the 223 grain P-belt will do good. If they shoot tight out of the slow twist barrel that is. If not ive read the ball-ets do a good job with that twist. Just have to order some and see.
