RE: .50 or .54??
i really like POWERBELT hollow ones for my .50 cal flintlock hawkins.
boy, they group nice with 70/80 grs of geox 2f.
i like idea i can SLOW THEM DOWN and bullet will open up nice on deer.
no kick to gun, less smoke, noise,flinching and load real easy without bore butter in winter out in woods.
i use 295 gr ones but i heard a lot like the 348 gr ones.
the 348 gr ones are about same length as the best bullet made for years for the .50 cal hawkins, the 370 gr MAXI-BALL .
nothing that will ruin your hunting more than a flintlock that kicks your head off and blows a bullet up on side off deer.
using POWERBELT hollowbullets at high speed and close shooting under 100 yds,is biggest mistake we can make hunting deer.[:@]
