I have not shot black powder for twenty years now. Recently got the urge when I ran across a nice Thompson Center Hawkin 45 with the 1-48" twist. Had some issues with the bore being rough but since has polished up real nice. I built a bore light to look at it and it's beautiful now.
My question now is I'm using CCI #11 mag caps and they are fragmenting upon firing. Sometimes just split, other times almost gone completely. Seems to be a bad thing so close to my face. Is this normal?
Gorex fff, 50gr, pillow ticking patch with a cast round ball.
I appreciate any information,
David
