Hello fellow collectors, I’m Tim, ECRA member and cartridge collector especially of armor piercing cartridges from Germany. New to the forum but a long time reader.
I searched for old topics regarding the FN 7.9mm AP cartridge but didn’t find what would answer my question.
Per my understanding pre WW2 / WW2 FN 7.9 AP are quite similar in design to the german SmK bullet regarding ogive, material and construction, cannelure. It is as far as I know steel jacketed with a full length steel core.
Sadly I have no samples on hand but seen pictures of postwar 1950s 7.9 Mauser FN AP cartridges (presumably Egyptian contract) which seem to star a different bullet. Judging from pictures, those newer bullets have a bit ‘fatter’ ogive and the cannelure is rolled in a way resembling the double cannelure of the 7.62 NATO FN P80 AP bullet.
Surely FN will color and crimp bullets to whatever the customer specifies, but I am curious if they changed the jacket to gilding metal or brass after the war and if FN might have changed overall construction of 7.9 AP bullets akin to the P80 bullet with a shorter penetrator, no lead sleeave and lead base. Bullet measurements / weights / drawings / cross sections would be appreciated.
I have pictures of the cartridge on hand but refused to post them in the first place since I was concerned about copyright issues.
