Well that's what you get for shooting one of those cast frame Rugers.

They give you the impression that they are stronger because they use more metal.
A friend of mine screwed up when he was making up some light practice loads. He wanted 2.5 grains of 231 in a 38 special with a 158 grain bullet. He weighed the charge and adjusted his powder measure until he got 2.5 grains then after it was set loaded up a batch.
At the range he loaded the cylinder and took a shot.
KABOOM! Gun was ok but it sure as hell was no 2.5 grains. It was too hot for him so he asks me to take a couple of shots. Yeah that sure as hell was no 2.5 grains I tell him. I then tried to extract the cases out of the cylinder. I had to pound the extractor on the bench a few times in order to get the cases out.
So what did he actually load in the case? Would you believe 12.5 grains of 231.

He didn't check to see if the 10 grain weight was on zero. Didn't seem to have any negative effect on the Smith & Wesson revolver.
Ok so it was a old N frame 357.
