I bet your erratic velocity with 4350 is cause of lower case fill. I’m running the 131 HHH in my regular 280 with ACC 4350 at a slightly compressed 58gn with no pressure signs (even today @ 95°). I remember the gun not liking 4350 till 56 gn I think.

Adding more:

N560
57 - 2963
58 - err
59 - 3085
60 - 3139
61 - 3203. No pressure. Still a little room for more powder. 5" vertical string at 200y.
61.5 - 3259
62 - 3256 sl ejt
62.5 - 3340 sl bolt, ejt
63 - 3369 hard bolt. Stop.

I think I'll explore around 61 gr for ~3200 fps. Not bad for a 20" barrel.

Ramshot magnum
62 - 2846
63 - 2881
64 - 2943. No pressure. Case almost full.

3 shot group of 57.5 gr Staball 6.5 was 1" at 200 yds. Velocity wasn't too consistent. This was the end of my shooting session, so chamber may have been getting warm: 3138, 3155, 3192.

Same rifle: 20" 1-7 6.5 PRC, 125HHT, CCI 200, COAL 2.850, no crimp

H4350
53 gr - 2952 fps
54 gr - 2987 fps No pressure, still room for more powder.

3 shot string of 56.5 gr staball 6.5
- 3048, 3063, 3084 (3065 avg) 1 MOA

3 shot string of 61.0 gr of N560
- 3210, 3225, 3253 (3223 avg) 1 MOA

Starting to question the Pro Chrono. Why now the group velocity is the same as 70 velocity? And group shot 10 degrees cooler. May be time for the Magneto.
