I found some pmc 9mm 115 gr jhp but on the top of the box there is a sticker saying for use in rifles only.There is more available with it all being the same ammo except some of the boxes have this sticker and some don't.I beileive this is from the eighties era.There is a 9B on the end of the boxes as well.I bought this for use in a 1911 pistol but now I'm concerned about damaging my gun.Anyone remember this stuff from back in the day.I'm wondering if a heavier recoil spring would make it safe.I also have some .45 acp military from 1944.I don't think it's corrosive but wondering if anyone can confirm that.One more,i have access to a bunch of Canadian military 9mm ball from the seventies.Its marked mk 1 on the box.Is this pistol or carbine ammo?Again I don't want to use it in my pistol if its to hot.Made by ivi.I don't know how to post pics unfortunately.
