Thumper beat me up again today, my Sharps in .45-90 didn't help much either.
OTOH I managed to get 8 out of 10 of my latest 405 (457193) boolits into 2.5 inches.
The first flier was due to an oily, unfouled bore. The other....well that's the reason I call the little brute "Thumper"!
Having shoulder issues these days and this project isn't helping.
