Common Alloys And Their Uses

[fiver]

yep. back when it was more likely to hear take that dirty stuff out of here so I don't have to dump it in the dumpster.
or, you got a bucket to swap? if you got a bucket take mine and replace it.
which worked out good because then I could put a bucket with my name and phone number on it and continue the routine every 5-6 weeks with no questions asked by the guy doing the tires.

then when I turned the 55 gallon drums full of steel clips in, I'd swap payment for whatever I could find in the lead bucket at the recyclers.

I still get a little excited when I hear of a stash of lead somewhere, even though I haven't even bothered melting down the stuff I have sitting out back yet.
I probably don't need to between that, what's already cast, and the ingots sitting under the bench, but I'm gonna follow up a lead in a month or so after the snow melts enough to go look at a barn find my buddy made.

Lets try pics again... Maybe better late then never.. Out of context now. But I was replying to hardening with PC in Quenching.

Just and update.... as to where I am at based on my original post.

My situation has changed a bit. I have managed to come into a windfall of indoor range lead. This range only allows 22/17 rimfire and non-magnum handgun calibers. I have 150lbs of it so far. I plan on getting about 600lbs total of it and then smelt it and mix all together for a consistent alloy. Not sure of the yield on 600lbs after the copper and impurities are removed, but I should have enough lead for the foreseeable future. I also have 60lbs of 4.5As/95.5 alloy, and am buying around 200lbs of clip on wheel weights.

So my plan is:
Try all projects with range lead +1% tin in the future.. Powder coating anything above 1800fps
Mix in the two other alloys as necessary depending on the situation needed
If all else fails, mix in superhard. and or magnum shot Doubt it will come to this.

This is basically what's it's like living in a post-CWW saturated world

" What would you do with your alloy here to get max accuracy. Let's not go with full jacketed velocities for this exercise, but perhaps above 2kfps where stuff gets tricky. Real life example of a problem to solve. 1903a4 30-06. Desired 1 moa @ 100yards. Somewhere around 2300fps. 150-180gr bullet."

Throw out the fluke three shot group and 1 MOA out of a 1903A4 is pretty much pie in the sky. Accuracy to me means on demand 10 shot groups. 2300 fps with an cast bullet out of a 1-10 twist barrel is most likely a fantasy. Sure, there will be people that will tell you, they do all of it on a regular basis, but...........

It's the speed that is the problem with my 1903a4. Low speeds like 1150-1300 fps is very easy to get 1moa.

change to a proper design.
2300 is low end starting to get there speeds.
