It's probably due to harmonics. I've used .01 ladder up or down and found the accuracy node very quickly with hammers. I've also used tuners if I want to keep velocity. I've got 5 rifles dialed in now using these methods.
I did try varget, maybe the min and max was way off. Do you know if a reasonable range to start?
Thank you
36g I'd say
I was hoping you would chime in. QL shows 42.3 as 99%. Powder is at body/shoulder junction. I shot 3 rounds with IMR 8208, but speeds were around 3800 so I didn't bother finishing up. Accuracy was only slightly better.
I'm considering N140, IMR 4064, RL10X, RL15, H4895 and BL-C(2). My powder cabinet is full, so any suggestions are likely in stock.

I can fix you up on the die
Give me a call this evening 812-264-6183
Will do.
Anyone have some load data for 7 Saum with 155 HH?? Building a tikka with 20" c6 barrel, wanting to get some loading supplies on hand while i wait for build to get done. Suggestion of powders and expected speeds would be excellent! Have some H4350 and H4381sc but willing to track others down if necessary. Will be using ADG brass.
Thank you for reaching out with advice and encouragement. I thought
i knew the answer, but hearing it from you was a confidence booster.
Back out today with the 22-250AI and the 44 HH. ES, SD and accuracy (100 yards) much more to my liking, I left the range with a smile on my face.
Varget
42.8: 4167 fps ES 24 SD 10 Group 1.22"
43.3: 4252 fps ES 18 SD 8 Group 1.07"
43.8: 4285 fps ES 10 SD 4 Group .62"
44.3: 4337 fps ES 5 SD 2 Group .47"
44.8: 4413 fps ES 28 SD 11 Group .51"
Still no sign of excessive pressure. Plan on testing 45.3. May have to get out the drop tube and electric toothbrush.

Looks like 44.3 would be acceptable.
