The only way a 1:11 or faster twist is going to shoot better then the 1:10 is if the 1:10 is damaging the projectile, which I highly doubt it would be.
Looking for perfect 308 bullet and barrel combo

The only way a 1:11 or faster twist is going to shoot better then the 1:10 is if the 1:10 is damaging the projectile, which I highly doubt it would be.
Care to elaborate?
With the 11”t the 185 is fully stable, and spinning less rpm.
I’m not sure why you think the 10”t will damage the bullet?
I don't think a 1:10 will.
But the only way that a 1:11+ twist would shoot better then a 1:10 would be if the 1:10 was damaging the bullet (either shredding/damaging the jacket or deforming the core). Otherwise, there is no advantage of the 1:11+ twist over a 1:10.
My .308 is in 1:10 and I primarily shot 168's and 175's through it. Zero issues, precision is great.
It's made by a gentleman who knows what he's doing, and has supplied rifles to over 800 alphabet agencies.
My Winchester match rifle has a 1:10 and Ed Begg used to shoot 185 Juggernauts and heavier out of it in FTR - and win.

My .308 loads and rifle are almost identical specs to yours listed. I shoot 185 JGN over varget fron lapua brass out of a 24" 10-twist barrel at 2550 fps and shoot out to 1000m with good success. That's a medium load in my rifle with no pressure signs. It is loaded long in my AI mag.
HANDS DOWNS THE BEST LOAD I HAVE EVER SEEN IN A 308 WIN WAS AT THE F CLASS CHAMPIONSHIPS IN OTTAWA 2017 SHOOTER FROM OTTAWA SHOT 49 B BULLS ONLY ONE OPEN C LASS SHOOTER SHOT ONE MORE V BULL WITH 50.
THERE WAS BRITS SHOOTING 155 GR AND OTHER SHOOTING 168 BERGERS,185 JUGGS,175 SIR,200 GR plus.
powers used VT 149,150,VARGET,H 4895 ETC.BYE FAR THE BEST WAS SHOOTING, BARTLIEN 11.5/TWIST 31 INCH, LAPUA PALMA BRASS. VARGET,GM FEDERAL BERGER BULLETS.

Doing a quick and dirty strelok check, 850M would be the distance the bullet drops below 1300fps.
Which in my experience, is the threshold which SMK #### the bed.
You are surely going transonic at this point to 1000M?
Manitou, what was the final best combo at your 2017 nationals I’m not sure I quite got it?
Fifth wheel purchased with over 50% down payment, decided I’d stop thinning the precision rifles I wish to keep.
The 6.5 vs 308 debate was weighing too heavily in my brain.
Keeping my origin/manners/atacr setup in 6.5x47 for the 200m to 900-1000M shots
Keeping my custom savage/mcmillan/NX8-32x in 308 for anything from 200M to 800M
I’ll still rebarrel that 308 to start it off fresh for my 185 Bergers (or other bullet for all that matters)
Still wish to find a bullet/barrel combo thats really accurate and out to 900M
over250 shooters was the best load on the range, hey shot a 13 v of 15 at 800
Thanks all for the feedback!
Jerry, I had a screaming deal for many boxes of berger 185s from a local.
How will the M852 reamer react to 185s?
I’d want at least 2/3s of the neck engaged on the bullets bearing surface.
I will buy the barrel from you by the way
Btw I am not firm on the Berger 185s I could always flip them.
If you don't end up using the 185s and want to pass on that screaming deal, please PM me.
With my specific inputs in Strelok, it's 1320 fps at 1000 yards. Sorry, got my units mixed up.
