Home Forums Hunting & Shooting Hunting Rifles Hornady GMX and Accuracy

I've not had much luck with GMX bullets either and I've tried them in a number of calibers, both in factory format and in handloads. I've had such poor results that I won't buy any more GMX bullets for reloading and I've even pulled a bunch of 120gr GMX 6.5 CM Superformance factory loads just to get the brass! I've had such good results with Barnes bullets that I'm not interested in trying to find a GMX load that works well. I'll buy Federal Trophy Copper if I need a good factory load that uses a copper bullet.

When I first got a 6.5 CM barrel for my AI AW I shot three 5-shot groups using Hornady's 140gr A-MAX load (12, 3 and 6 o'clock) and then shot a 5-shot group using the 120gr GMX load (9 o'clock). This is a small data set but follow up tests with the GMX stuff didn't get any better so I don't waste barrel life with it. The AI will shoot almost any factory load well, and some exceptionally well, but the GMX is not one of them.
