You'd be fine with an 8 twist. Many go with faster twists but they also push much heavier bullets. I would say you could also do a 7 twist if you desire to go heavier in the future. Both 8 and 7 should work.
Impact 22” Benchmark carbon 8 twist was recommended to me by TS Customs for a build. Travis knows what works and builds some nice stuff that are easy to load for. Lots of good smiths out there and good actions too.
I would also recommend the 8 twist. Plenty fast for most bullets and keeps you from blowing those thin suckers up with a 7”. I’m running 90gr A-tips at 3k from my 18” 8tw
All my parts are at the smith as we speak. 23" rock creek carbon 8tw barrel, Tikka t3x action, jcs composites tactical stock. My plan is to run 70-80gr bullets with RL26 and H1000. TBAC Ultra 7 for predator action.
I have a 7.7" CarbonSix 22" barrel in 22 Creedmoor. Just started loading development for it. If I had it to do over again I'd do an 8 twist. It seems like guys using fast twist 7" barrels are blowing up bullets. If you look into that people seems to think bullets need to stay under 290,000 RPMs. If you do the math a 7.7" can only push 88's at 3150fps. MV(12/twist rate) × 60 = RPM. I guess that means a 80gr bullet in an 8 twist can do 3200fps. 3200(12/8) x 60 = 288,000rpms.
I see there is a lot of different barrel companies making carbon barrels. I have several proofs on other calibers and have been very happy and have one bartlein on a 300 wsm. Have not started on a load for it yet. Thank you guys for all the input. Nine Run Gun has built several of my rifles. Love his work.
