powerbelt in a flintlock is BEST bullet i have ever used.45 years hunting bucks with hawkins .50 cal .
but it has to be loaded MEDIUM .

i like 295/348 gr. loading my hawkins at no more than 80 grs and being able to not have RECOIL/SMOKE/NOISE/EASY LOADING IN COLD is great thing and bullet opens nicely on a buck.

shoot them in a in-line at high velocity,I WOULD NEVER DO THAT TO A DEER.
as most load their in-lines HOT powerbelt is not bullet i would use.
but in a open sight flintlock, ITS A GREAT BULLET .
