Ammo life span accuracy

[Kurt]

I had some 20:1 alloy money bullets [paper patched] that were excellent at long range until they reached 3.5 years on the shelf.
Luckily that was the last of that batch I had cast up. They were all over the map at 1K and didn't do a lot better at 900 or 800 yards.
I cast up more bullets with the same alloy [rotometls] and then I was basck in business.
I do not know what was wrong with those bullets after sitting on the shelf for 3+ years, but I am never going to cast a large supply
of bullets again.

Keep on hav'n fun!

Mike I'm beginning to feel the lead from Rotometal is not 99.9% pure like he lists it on the web page. Pure lead does not ring when you drop a Pig on the cement floor. I handled a lot of lead through the years I was a plumber wiping lead joints and wiping flashings as well as pouring lead joints. we used solder that came in 25# chain ingots 5# ingots linked together and I could tell by dropping a ingot or the whole chain on the floor and tell what is lead or solder by the sound.
The lead I been getting lately from Roto some of the pigs I drop on the floor it rings like a bell and the cast bullets from batch to batch do not drop from the mould the same weight at times. This makes me think if he is using recycled scrap or the people he has working boxing up the lead box up some of the already mixed alloy. I don't have a $4000. lab BHN tester to get a accurate reading on the lead so I cant say if it's 99% pure or not.

Even John Walters has been sending me sheet lead lately and that stuff has arsenic in it to keep it from oxidizing and makes it harder.
