in my hawkins T/C.50 cal flintlock the best bullet is the POWERBELT.it loads easy and is very accurate.nice thing about it i dont like a lot of recoil/smoke/noise.
those PB will open on deer at middle of ground velocity.
295 i like but the 348 is good too.245 dont use it.

i use no more than 80 grs of geox 2F or 70grs 3f with a bore button.

if i had in-line i would never use PB .unless you shoot very low charges.most i know want their in-lines at high charge.

IN FLINTLOCK,OPEN SIGHTS,SHOTS UNDER 100 YDS THERE IS NO BETTER BULLET THAN POWERBELT 295/348 AT MEDIUM CHARGE.
