I shoot IPSC and would like to make my own 9mm boolits. I'm currently using coated lead bullets, which work very well and are pretty economical. I like the idea of swaging more than casting (as no liquid lead / fumes). I'd quite like to stick to coated bullets to reduce lead exposure when fired. For speed of production, a coating seems like a better option than jacketing.
In order to make IPSC power factor, a 125 gr projectile needs to be doing a bit over 1000 fps. While obturation is great, I suspect the pure lead will be too soft.
As coating requires a heat cycle, I've been looking at quench hardening to take the hardness up a bit. However, pure lead doesn't quench harden, so you need to alloy it. Antimony seems to have the best increase, but will also take an air cooled 98:2 alloy to around BHN 8, which is I understand, much harder to swage.
So I'm curious if it's difficult to swage a standard 3/4-E from BNH 8-10 lead alloy? Can it be done in one operation (without a shoulder), including bleed holes to get the weight/dimensions perfect?
