RE: Is the 45colt case weaker?
Nomercy, if you section a Federal or Starline .45 Colt case, you will find they are Just as thick and made of just as hard an alloy as any .44 Magnum brass! I discovered this over 10 years ago!! I AM NOT talking about folded head, so-called " balloon-head" cases!! Those are relics of the Black Powder Colts!!
So, what you just said about the .45 Colt brass of modern manufacture is just flat WRONG!!!
