Luck coupled with a plethora of good information here led me to success the first time trying this rifle out. Ishapore rifle, Hornady match case fire formed and neck sized and M die, Winchester large rifle primer, 168g gas check tumble lube boolit cast from straight wheel weights and stuffed over 10g of unique.
I fired 50 rounds and there was ZERO leading. Some right nasty black filth that took a dozen patches to remove, but nary a trace of lead. Accuracy was impressive [to me]. I shot clay targets out to 100 yards with no effort. Shot this group with the last three rounds I had loaded. I wanted to see if fouling hurt accuracy. Shot at 50 yards with a pretty bad astigmatism.
