i have tc hawkins .50 cal flintlock. i hunt only whitetail deer, BUCKS ONLY no doe as not many left here in pa.my favorite load is 80 grs of 2f with a MAXI-BALL 370 GR. i used to shoot roundballs when maxi-balls were illegal here in pa.i also like POWERBELTS in 295 gr. with 80 or 90 gr of 2f.remember, the secret to shooting a flintlock is being able to hold on the target without fear of the recoil/noise. LOWER charges are way to go with heavy bullets.my hawkins is like shooting a .22 cal to me UNLESS i go to 90 or 100 grs which i dont ever use. i shot a lot of bucks with that load and maxi-ball 370 in in last 25 or so years i could use them.take care.
