So the only ammo I've gotten multiple failures from my new build is Wolf .223 Rem 62 grain HP. In conjunction with these failures, I'm talking almost every round fails to cycle/go into full battery, I have gotten the same type of failure from this Ammo once out of my Bushmaster and ZERO from any other type. Now I said this type of Wolf is the only Ammo I've gotten multiple failures from. . . I've did get a single failure of the same sort from Tula 62 GR. HP. Now the ONLY Russian production ammo that I've NOT experienced ANY failure from is Brown Bear. Now many of ya'll would say "Well it all comes from the same place." While that may be true, check out the picture I included. On the right is the Wolf, on the left in the Brown Bear. The "polymer coating" Brown Bear advertises is very visible. It also has a texture, much similar to brass as opposed to Wolf, which is much different. Also notice that the projectile on the Wolf (right) is a bit longer (seated shallower) by about 3/32" (yes I did measure). I wish this rifle would "eat everything" that is something that I want(ed) out of ALL my guns, especially ones to be considered for a SHTF grabber. As it stands the AK is still primary, (especially in urban, short range apps.) but this AR will get drug along. Hopefully the current build will out shoot this one, even in the accuracy dept., but consistent 200 yard hits on a 8"-10" plate sure beats out the AK. So. . . . . questions, comments, concerns does anyone even care?
