JHansen, EVERY reloader will end up reloading crimped primers, Especially for 7.62x51 you simply swage out the crimp so it'll be easier to seat the new primer.... You seem to have your reloading information reversed as its BERDAN primed ammo that doesn't get reloaded except for by a very few hardcore reloaders or in the case of calibers that have no option..... if you can even get berdan primers (very difficult to buy as nobody stocks them) they will cost you around $7.00 per hundred and have alot of assorted metric sizes, next in order to remove the old primer you will have to fill the case with water and use a tightly fitted dowle you hit the dowle with a hammer the hydraulic force pushes out the primer and sprays water all over you........
As far as the Canadian 7.92 ammo Don at Omega weapons had 30,000 rnds of it we linked up for use in the MG34s EVERY single round was a hang fire and split cases were very common at the neck with brand new un-issued barrels in the Semi converted MG-34s it was so frustrating we ended up delinking the stuff and it was sold to an associate of his who is licensed to sell ammo commercially the guy unloaded all of it at Gunshows at $2.50 per 20 rnds last year...... The 50s Yugo stuff is MUCH more reliable outa the 50,000 rnds we have burned up of it at various machine gun shoots as well as in a large number of Milsurp bolt guns and semi converted MG 34s and 42s and 5 1919a4s there have been zero problems other than the occasional split case neck We've got Pallets of the Yugo stuff from 1953, 1954, 1955 none of it has had any problems........ We took a loss on the Canadian stuff just to get rid of it as its hard to sell a $3,000 gun if every round is either a hard primer that does nothing even with the hard hitting MG34 fireing pin or a CLICK..................................................................BANG the only ammo that performed worse was the Pakistani .303 he bought in bulk but its a tossup there as to which was trully the worst
12.99 for 44 rnds is not a cheap deal for surplus especially when you can get truly reloadable BOXER primed commercial 8 mm mauser like Wolf gold, S&B etc...
