It is a sickness, yes.

It is a sickness that, if you are not careful, can make you sick. :)

Yes. I've even had to called in sick before because of it.

I have about one more month before I start casting again. After my recent high lead levels I needed to give my body a chance to get back to normal.

All I can say is that no matter how much fun it is nor how much money you save, be really careful! It is NOT wort it to be sick or die over!

There is NO speed your .45 can produce safely that a 9-12BHN bullet won't be more than adequate. It is good to about 1500fps and 30ksi. Your .45 ainlt going to get near the limits of that target alloy.

Soft can obdurate and seal the bore. Super hard 18-22BHN alloy can not obdurate at .45 pressures and must be well over groove diameter to not lead.

If you get a .45 Win Mag, you "might" need that HARD alloy.

I have changed everything now. I have a bunch of bullets already cast so I will be shooting those in bolt guns mostly now rather than my AR, which is where I think I got most of it. I will be more judicious in wearing protective gear. And finally I will be powdercoating all new bullets that I cast.
