KIK is a good powder. I was shooting that when there was the Goex shortage a while back. I found it a little more dirty then Goex but power wise, it was excellent. Also it igntied real good..

Sounds like you have your hunting load. 120 grains of powder with that large ball.. nothing wants to be on the other side of a 284 grain roundball that would be moving along like that one.. I bet the expansion on the round ball was real good as was the penetration..

Nice shooting there.
