Question about 38spl +P

[Mbaker78]

I’m planning on loading 38spl/357mag for the new derringer, and I was thinking about carrying 38spl +P instead of full power magnums. When loading +P, can I use brass that’s not marked +p?

Check out the thread below. It seems that no one could find a consistent significant difference in weight between regular and +P .38 Special brass. It would stand to reason that if +P .38 Special brass was more robust in construction (or regular .38 Special less robust), then this would show up when weighing samples of each, since dimensionally they are the same.

Cool, thanks.

I think the +P markings were just put on so you wouldn't stick them in a non +p gun. I don't think there was any real difference in the brass.
