after getting 4 ftf with the AE brass, and 1 from tula, I concluded that my rifle doesn't like AE brass and I need to dremel the front of the mags so the front lip of the mags are lower
been doing some research and this is a common problem for these mags. seems like the round hits the front lip as its getting chambered
so I dremeled 1 mag of each. the ASC I didn't dremel as much.
so went back the next day to retest with same ammo: 2 boxes tula hp, 1 box wolf hp, 1 box AE fmj brass. total 80 rounds
this time only 1 ftf from the AE brass again out of the ASC mag which I didn't dremel as much
so now I will dremel more off the ASC mag, and get ready for more CPD mags that I ordered. the CPD mag seems to work now that its dremeled down some
here's a couple of pics comparing both types of mags before and after dremeling:
this is the ASC mag
and this is the C products defense mag
