There is no difference in non +P and +P brass, Only the headstamp. Buy some new brass, say Starline, does it say for 38 special only and do not load +P?? Click to expand... Starline standard pressure and +P marked brass is not different what so ever other than the +P marking which is used only for identification purposes. I read this directly on their website.
