RLH70,

Thank me very much!

Wayne,I would try sizing bigger and using a slower powders before I tried heat treating boolits for a 45ACP.I size mine @.4525 and,if I'm pushing them,I'd use Unique or slower powder.

I shot 100 bullets this weekend that I hardened a week ago and found much success!

These are the same Lee 452-228-1R that I was having so many problems with earlier in this thread. The only variable that I changed is I heated at 400F for 1hr and water quenched, everything else remained the same. It was 8 days between casting and shooting, so they had plenty of time to harden. The leading isn't completely gone, but it is MUCH less than it was with the unhardened wheel weight lead. As a matter of fact, I shot the whole 100 through my 1911 and checked for leading about every 10 shots. Normally I would stop at about 50 fired because the leading was causing flyers, certainly not the case this time.

I think I'll try hardening just a bit more and see what that yields.

Glad to hear it's working Wayne!

Missouri bullets has a writeup on bullet hardness and velocity . I thought it was interesting. I doubt I will get in to bullet casting "I hope"
