I've been running through factory ammo in my p32 and now have enough brass to think about reloading some now but was just wondering if this round headspaces on mouth or rim. That little rim is enough to cause rimlock troubles but I don't know if it is enough to headspace off of but when I was working up squib loads in 32 (near silent shooting under house with lead balls) I noticed that the dies were capable of putting a serious roll crimp on the cases which would prevent headspacing on the mouth like 9mm. Puzzling????
