Yes. This is not my thing per se.
I'm helping a buddy that's heavy into trap shooting. Reloads his own shells. But he's been finding 7-1/2 shot hard to find firstly and secondly getting pricey. He's going to try making his own shot. I can supply lead but it's supposed to be "hard". The number is supposed to be 6% antimony for that. Although manufacturers won't give anything more than "hard" for a description.
I cast 9mm for pistol out of the soft lead and coat it with no issues. Also .308 for 300BLK subsonic.
