got a sack of 45acp brass,(1st time fired) started to deprime and see some are lp some sp .both have some with elongated primer pockets...safe to use or??/ thanks
I am betting it is the top of the primer that is elongated. When you remove the primers inspect the flash hole. If there is a little scratch that will be OK to use but anything deeper than 1/2 the depth of the flash hole is a bad one. A picture would really help. The recent times have given us smaller sized primer pockets but they load the same other than size. At least in my loads they make no noticable difference in accuracy or function. I now save the small ones to use if I should run out of large pistol primers due to supply disruptions.
Those pictures shore look the primer pocket is not round. Wow never seen that before either. Might have been made that way. Did you decap them all or can you inspect some of the others. If they dont leak gasses i would try loading a few and see how they work before scrapping a bunch.
