Since I purchased my first center fire many decades ago I have reloaded and have purchased very little factory ammo. This summer I purchased a new M1A and also bought (15) boxes of 7.62 x 51mm Winchester Service Grade ammo. Enough to tide me over until I could find primers, bullets, and primers. This factory ammo is Lake City brass. So far I have had (4) neck splits on the first firing, (4) primers blow out, and three that failed to chamber. The cases with the blown primers had a primer pocket that measured .020" bigger on the I.D. than the diameter of my primers. The (3) that failed to chamber also failed the case gauge and had to be resized. Thank goodness I only have 30 rounds of this left.
