I got the 54 1 in 66 t/c renegade tacking driving them round balls out to 100 yard from the bench.I did boost the powder charge to 100 grains of goes 3 F 230 hornady R/B .017 blue and white patch and 3 shots at the 100 3" groupe with Fiber optic sights
Next I wanted to see how my 50 cal. flinter shoot the buffalo 325 grain HPBT bullet/sabot in the older 50 cal barrel made buy douglas
Man outstanding 90 grains of 3F 3 shots again maybe 2" goupe at the 100 yd target also but this barrel wears a rear peep
