Your first comment is one of the nuggets that are hidden in this forum. Fascinating fascinating. When I was a kid, my dad told me about the shot towers and how it was made. I tried to do the same thing (ever see a kid pouring molten lead off the roof of his parents house? LOL!) and found just what you said, the shot didn't come out like anything but splatters. I always figured it was because I wasn't high enough, but if what you said was correct, then it was the COWW alloy I was using. Thank you sir! that's been bugging me for years.
So you're saying that adding magnum shot to the alloy is about as good as it gets because .2 % arsenic is all that can contribute to the hardness of the bullets? (please correct me if I misunderstood).
As to your second comment:
Yeah, I didn't think that through all the way. HTed bullet = hard bullets. Duh.
Precision in the wrong place is only a placebo.
I'm having a REALLY hard time understanding why entire threads are being given the Uncle Joe treatment instead of having the off base posts excised. If the thread is gone, the controversy is gone? Is that the logic?
Anyone and everyone who read these threads get SOMETHING out of these threads.

Have you guys tried water quenched magnum birdshot.
That alloy and heat treatment has been written about extensively by Frank "Paco" Kelley. He sells a book about his loads also. He has used it to go to full jacketed velocity/accuracy in quite a few firearms.

Knowledge without understanding is a dangerous thing. For a little knowledge entices us to walk its path, a bit more provides the foundation on which we take our stand, and a sufficient amount can erect a wall of knowledge around us, trapping us in our own ignorance.
Never sleep, never die
Knowledge is easy to get, but worthless if you never use it. However the info is free, so the only person you have to blame is yourself if you chose not to use the information.
Arsenic is a grain refiner to lead, that's how it works to make it "hard", by reducing grain size, like the difference between OSB and particle board.

All in good time sir! Cu alloys is one of the four methods I want to learn before its all over.
Yes, I am behind, and I beg your pardon, and that of the participants. I've been away getting rid of a stress induced ulcer. Trust me it's better this way! I've got a long weekend coming up and I'll try to catch up.

Tim, here you go. We have a bunch of these all over the place.

Hey Tomme, good to see ya!
Yes, I know what a shot tower is. Dad wouldn't let me build one, and told me to get off the roof with my lead pot. LOL!
BTW, Did you make any more headway with your rifle?
Precision in the wrong place is only a placebo.
Won't need heat treat or gas checks? Got some targets and chrono data to back that up?
I seem to remember the MI guys using a check design and water droppng the bullets. Not sure who around these parts has done more work with the Cu alloy than them.
Take a look at this link. http://castboolits.gunloads.com/show...s-this-further
Specific mention is made by Mike to water dropping, a form of heat treating. One of the bullets he mentioned in his comments about the Cu alloys was very similar to this one. http://castboolits.gunloads.com/show...-grains/page28
Looks like a check and heat treating might just be a good idea even with the Cu in the alloy.

You will learn far more at the casting, loading, and shooting bench than you ever will at a computer bench.
can a solid copper round bar be pressed formed into a bullet shape? i wounder how much pressure would be required.

Yep, I'm sure it is. Even then is it practical for most of us? I don't own a hydraulic press and I'm sure the dies aren't cheap.

the die is probably the most tricky part. for smaller bullets like .223 caliber, maybe a 20 ton jack would be enough.

I thought Barnes lathe turned all their bullets.
Regardless, most of us are doing this because it's fun and cost effective. I've made solids on the lathe, and it's neither.

The X-bullet has a formed hollowpoint. The hollow may be lathe turned but the posting would occur following that.
Even if lathe turned it isn't practical for most and certainly isn't a "cast boolit" by any stretch.

in the context of this thread, i thought opening the door of this idea was worth posting, even only if the if the door of the idea was closed very quickly after.
kind of thing ....

Nothing ventured nothing gained. Outside of the box thinking is what is needed to advance the art of shooting cast.
