Rate of twist isn't the only factor in stabilizing projectiles, a bullet pushed through with higher velocity creates a faster spin, and the higher RPM is what stabilizes the flight of the bullet.
So if i understand correctly, a higher fps load could stabilize equal to or better with a 1-11, compared to a slower fps load coming out of a 1-10 or 1-9 barrel?

So i just need to work up a hot load?

Velocity has very little effect on stabilization. Twist rate is by far the biggest factor.

Play with this twist calculator and you will get a good idea of the different factors affecting stabilization.

I would not mess with any of the 270 ABLR's based on the thread that Lefty posted.

Savage Model 11 FCNS in 270 WSM has a 1-10 twist. Are you sure your Savage is a 1-11?

Savage changed to a 1-10 twist in the 270 WSM but there were some years that they used a 1-11 twist, you have to verify the twist rates with a rod. I had no issues with stabilizing 150's in my 1-11 twist but I'm at 6000+ elevation, the ALR is an aggressive design so it may not do well in the 1-11.

Re: Savage 270wsm 1-11 twist

Went down this road with some 150's in the same barrel. Never did get anything that would hold a good group. I believe we ended up with some 140's that worked out. Been so long I can't even remember all the details. Just 150's bad...lol
