Ammo life span accuracy

[MikeT]

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!
