New to loading 38sp. What is the difference in +P brass as opposed to non +p brass? one thicher than the other? If so are there any special considerations to be aware of?

38 SPL+P has no difference from the standard 38 SPL, other than headstamp designation for load segregation. Due to standard case design, will handle +P pressures with no problems.

Now Starline Brass Co claims their 45 acp +P brass has a thicker web.
