Of course, I use Speer's plastic training bullets, which are powered by primer only.
Nope. That's why I can only draw and fire once. Or do a "tap/rack/bang" drill. I suppose they're really intended for revolvers. But they work fine in my .45acp, 9mm and .380acp. Drawing from concealment and getting the first round where you want it, fast, is the most important part of the process. The rest you can practice at the range.Will those cycle an action???
I'm aware of the danger, and yes, the garage has great ventilation. I would be careful about a basement, though, for the same reason. If you can ventilate it, and sweep the floor regularly, I would feel fine.Unless you got a real good ventilation system in your garage, I would highly recommend against it. The primers you are using produce a significant amount of lead vapor.
