I've shot a fair number of Cutting Edge bullets in .375s and .338s as well as handful of 7mm and .30 cal.
The 375s were shot in my wildcat 375 BME (375 RUM improved) with a 10" twist Brux. My base line bullet/load was a 350 SMK at 3050fps from a 30" barrel and it shot .75 MOA out to 1720 yards averaged out over the 325 shots fired with that bullet at that range. The CE bullets I tried were the 330gr MTH (3120 fps) and the 352 MTAC (3020 fps). I worked up a load with both bullets that would hold .5 MOA at 300 yards then moved to 1020 yards, 1380 yards, 1618 yards and 1720 yards. I was never able to get the CE bullets to hold consistent groups beyond 1000 yards. I would get 2-3 good shots, then on that would seem to just drop out of the sky. On multiple occasions we could watch the bullet trace out to 8-900 yards and then it would just go off into no man's land. Based on what I was seeing I came to the conclusion that the CE bullets weren't adequately stabilized. My best guess is that they were "slipping" in the rifling and not being fully stabilized despite having an appropriate twist rate and Sg on paper. I believe that with the right balance of velocity, bullet weight, twist rate and bore dimensions they can shoot very well and I've seen some people have excellent luck with them.
However I've seen similarly poor results with 275 MTH and 277 MTAC bullets in a 9" twist 338 Edge and a 9.3" twist 338/408 Improved, 190gr MTH in a 9" twist 300 RUM and the 155gr MTH in an 8" twist 284 Win. It was not nearly as pronounced in the smaller diameter bores, but there were still enough unexplained flyers or missed shots that I gave up on CE bullets and now I just use the ones I've got left for fireforming brass.
I haven't seen any of the same issues when shooting the Hammer Hunters. If I'm getting good clean holes at 300 yards, I'm getting consistent groups out to 1700 yards and farther. Just pick the right bullet for your twist rate and you're good to go.
The the 304 gr Hammer Hunter is my go to bullet in the 338/408 pistol when I shoot it out past 1 mile. The 300gr Berger OTM shoots well and has a higher BC, but the 304gr Hammer just shoots better. I save the OTMs for when others are shooting the gun or when I'm just messing around.
