Re-starting this thread.....
What the heck am I doing wrong? I just got a 28 Nosler Edge. I've now got over 200 rounds down the tube with 180 Hybrids & 175 EH using Retumbo, 8133, and 7977, and cannot get much better than 1 moa at 200 (.75moa is the best, with both bullets at about 0.070 jump; most groups 1-1.3 moa). I've run through the Berger seating refinement, then testing charge weights. I'm using Redding master hunter dies, with a .314 bushing. Necks are turn just slightly to clean up, with tension about 2.5 thou based on loaded case. Dies are set in a Redding T7 with a bit of cam-over, per Broz' videos on LRO, and using Redding Pro shell holders to give me just enough re-size on the FL die to allow clean bolt close. I am keeping the barrel religiously clean. I've checked the rifle, set the actions screws at 70in-lb, cleaned up a couple light-touching spots in the barrel channel. Shooting VX6 3-18 in bedded Talley mounts. Pretty much seems no matter what, I'm at ~1+ moa. And, fwiw, accuracy nodes seem very narrow, like 0.3 - 0.5 gr. I still have further testing to do with above powders & 175 EH & ABLR next week.
I've got a bighorn sheep hunt, and elk/deer coming up in 2 weeks in MT. To say I'm getting frustrated with a $2700 rifle would be an understatement.
Any input from our fellow shooters here would be appreciated.
Thanks!
