Have ya'll done any testing with this bullet in 300 RSAUM? I have tried to get the 168 and 155 J4s to group well, but I always get a first or last shot flier. A typical group with the 168s will be about 3/4 MOA, but with 175 SMKs I am averaging 1/3 MOA out to 535 yards and the 178 AMAX will hold under 1/2 MOA to the same distance.
Both bullets are superb in a 308, but at 2950-3200 fps, I have not shot any real good groups. What have you observed?
Really like these bullet. IMHO it is better than Sierra MK side by side comparison using my 308 Tactical rifle. You be the judge. Flyers were my fault. Sierra MK on the left and Nosler J4 Comp on the right
