Try other bullets including the ones you haveI’ll try jammed and also more powder.
If that doesn’t work, I’ll order a 7 twist barrel.
also have 105 AMAX and 105 BTHPs I could try, I just prefer Bergers.

I can’t speak for 105 hybrid however the 107 sierra over 30.1 Varget shoots well in a 1-8 twist as per this 550 yard sampleWhat is considered “hot” with Varget? I only tested 29.0-30.0. Granted I only shot 3-shot groups, but I do that as a quick recon, to identify the bad. Groups and ES won’t get better from 3 to 10-shot groups.
with that said, 29.0 and 30.0 performed the worst. At 30.0 I was
Pushing the 105s 2824 fps. But group was 1.80 moa with an ES of 39. Unacceptable. Notes attached.
The data with a / is data from Magnetospeed/Shotmarker. I don’t depend on SM data, it’s just another reference and to see correlations.
wow---i have lived a sheltered life---i have never seen a custom/aftermarket bbl that looked that ruff !!--is this a savage or budget item--if a bullet runs over that cheese shreder it is going to be streaking copper all the way down the bbl and the torn jacket will not allow the bullet to fly right (in my humble opinion )--I would not waste any more components on tht rototiller of a chamber --life is too short to spend time trying to make that disaster shoot--Rogerwill check out the rifle and scope etc for anything obvious. I did scope the barrel and noticed these machining marks on the lands right at the end of the throat. Other than that, barrel looks good.
testing was at 100yds.View attachment 1324712View attachment 1324713
Yes, I would and did. It shoots very good. I did it just incase I decided to shoot something heavier. I'm sitting on about 6000 DTAC's.If you guys were building a straight 6BR to shoot the 105 bullets and 107 Sierra’s and 108 Berger’s would you choose the 7.5 twist over the 8 twist? I’m at 2650 elevation.
My 1 - 8 Tw. 6BRX shoots great but if I do another one I will go 1 -7.5 Tw.If you guys were building a straight 6BR to shoot the 105 bullets and 107 Sierra’s and 108 Berger’s would you choose the 7.5 twist over the 8 twist? I’m at 2650 elevation.
Just picked up a 1:7.5 for my next 6br.Thank you both! ^^^^^^
All of my 6BR barrels have been/ are 1-7 twist. I'm of the "better too fast, than too slow twist" school of thought.If you guys were building a straight 6BR to shoot the 105 bullets and 107 Sierra’s and 108 Berger’s would you choose the 7.5 twist over the 8 twist? I’m at 2650 elevation.
