Yes, it's good. Alloyed 20:1 with tin, it works well in rifles .30 cal and bigger up to near .30 30 velocities, as long as the bore is smooth. Higher velocity is better done with about 5% antimony and 2% tin.

20/1 lead/tin is a BPCR alloy and is soft only around 12 BHN id not use it in a rifle other then a BPCR
I would use that alloy in a rifle, but not over 1200 fps.
