The short answer is no. Some may tell you that they're stronger than regular 38 cases, but I rather doubt it.
I do like them however, for loading actual +P loadings. Call it tradition or OCD (
) or whatever, but when I load a +P round, I like to use +P stamped brass. Just me.
Bottom line: Unless you're an odd one - like me - just treat them the same as your other 38 brass.
