I picked up about 150 Federal .38 Special cartridge cases at the gun club today. Later I started to pop out the old primers prior to tumbling the cases. On the 1st case I noticed a lot of resistance to the primer coming out. I looked at the primer pocket and saw that it had a crimp ring. All the cases are Federal with identical head stamps and cannelures in the same spot. The only difference is the crimp ring on about 2/3 of the cases.
My question is has anyone else run into crimped primers in .38 Special cases? I can't see the point in it. I've picked up a lot of Federal 9mm cases that appear to be commercial ammo that have crimped primer pockets. I can understand 9mm but not the .38s.
Have any of you run into this?
