My nephew wanted to go shooting so we scoped the Evolution, took 2 shots at 25, made adjustments and then he took 2 more at 50 yards. He has a 4" spread ( he insisted on shooting standing up) And he was done after that. I took the last 2 remaining shots @ 50 yards and was amazed at the group! 2 shots touching 10 o'clock.

70gr Pyrodex RS
CCI #11 Mag caps
.490 round ball
.020" ox yoke patch

It seems be be an excellent load for 50 yards. No muley would survive that hit. I plan on trying this out next time at 100 yards to see how it groups.

I have shot round ball out of a number of my inline rifles with excellent results. The trick was not to push them too hard. My Knights actually shoot round ball real well.
