I have to agree, save the steel cased stuff for what it was designed, being shot out of a Communist rattle trap by an expendable soldier.Steel cased. Some say it is ok. I say that for a $1400 rifle, I will stay away from cheap ammo.
There is also some Pakistani Ammo to steer clear of.
WWB is ok, I guess.
Mine loves the Mil Surplus stuff.
Ammo that is lacquer coated may bring issues as well.
Hope this helps.
It works fine. It's actually a copper-nickle jacket over a lead core, with more nickel than copper, so it looks white instead of coppery. Nickle is a magnetic metal, and there's enough in the jacket that the bullet slightly attracts a magnet, but it's NOT steel or iron cored ammo.Oh and besides the difference between dag and men, is a nickel plated round honestly ok to fire out of an m1a?
