Does anyone know if Cast bullets get Brittle as they get Old(15+ years old)? Went to the Range today & shot some Old .45acp Reloads I inherited from a 97-yrs old Uncle that recently passed. The loads were probably at least 15 years old & Not "Hot." One of the Cast Bullets broke off, even with the end of the Case (While in the magazine) leaving part of the bullet still in the case & part in the bore. I stopped shooting those rounds at that point & that part of the bullet in the bore was easily removed. Don't know if I should just chuck the rest of the batch (aprox 200 rounds). Pretty sure the Cast bullet recipe was Lead & Antimony.
