There's a simple reason for that


"Nothing we're going to do is going to fundamentally alter or eliminate the possibility of another mass shooting..."
-- Joe Biden

That's because it's not intended to do so.

Is there a video or transcript of your presentation at Lecompton?

BW: Best that's available is this newspaper account. I wonder if I can attach my powerpoint here - that would give you a lot better idea than the paper.


Giraffe: One of the things I've learned about zinc is it is very bad for making cast bullets. As in a small amount ruins your alloy permanently.

I read that - it seems that many many people have made that mistake, usually by missing a zinc wheel weight or 5...

But I did read a piece by a guy in Germany who couldn't get lead, so he cast bullets with 100% zinc. He claimed it worked just fine.

I may try it, but it would be a last resort.

I just read about pure zinc boolits* the other day.

The correct term is in fact "boolit"

I have so much to learn...

Giraffe said...

I am a beginner myself, having cast only a hundred boolits or so.

Once you've cast, do you harden them? Add gas checks? And if not, have you found them to fire measurably dirtier than FMJ?

While I'm a stickler for a clean gun, I can't say I enjoy cleaning it enough to do more than I have to...

I have done nothing but cast, lube and shoot.

I bought Lee tumble lube dies. Supposed to make it simpler. Somewhere I read that these don't need to be sized, so I haven't done that. It is very simple, but...

I measured some bullets and they are a few thousandths out of round. Now, I am thinking about buying a sizer. But first I should see if it even matters, accuracywise. I'm not sure I'm a good enough shot with a handgun to tell.

As far a gas checks, I haven't used them. I've been reading quite a bit in some old Handloader magazines. I guess Elmer Kieth thought gas checks were a waste. They are unnecessary if your bullets are of the proper hardness and fit your gun. Might be easier to use a gas check than get all that right. In a rifle cartridge, a gas check is needed above a certain power level.

I was always biased towards jacketed bullets, but I've learned that in a handgun at least, a cast bullet is no handicap.

I haven't noticed much in the bore for fouling. Hard to see down there. Leading in the bore is caused by improper lubing or gas blow-by. Blow-by means you are pushing too hard (need a gas check) or your allow is too hard and the bullet doesn't upset to fill the bore. I understand leading can be a pain to get out.
