I discovered that factory Hornady 120gr GMX ammunition doesn't shoot well in my 6.5 Creedmoor so I used an RCBS kinetic hammer to break down a couple of boxes to use the brass. I'm saving the primers for other loads but tossing the powder. Since I have 200 rounds or so of the GMX stuff I could try working up a hunting load that actually shoots well. I typically use Barnes bullets for hunting but if the GMX bullets are capable of decent accuracy it might be worth the effort. The target below shows factory Hornady 140gr A-MAX 5-shot groups at 12, 3 and 6. The group at 9 o'clock is the 120gr GMX load.
