non lead solder is so hard, Lee lube so

good, that bore fouling is not bad, even at 2000+ fps, even with big, deep hollowbases on the bullets, and huge charges of Bullseye powder. Such bullets are far too expensive to even shoot matchs with, much less plink with. No more rounds than you are going to fire at either animals or men, the small amount of fouling in the bore is not an issue at all.
