Just over 550 out the window of a truck with an AR15 and 75amax bullets. It worked just fine
How’d you get 75gr a max into the magazine? Single shot sledding?
2.39 is ogive at the case mouth if memory serves
Shot a pile of animals at 500 with a 223..
Does good work.
75gr eld-m work well. So does factory 77gr tmk from black hills ammo.
