I have 1:9 and a 29 inch barrel. I was looking at a 27 Nosler last month and it was something like 8.5 twist.

I was able to shoot up to 175 or 169.5 which i have the most pills of. The 190's were no go! I wish that i had the formula to post. twist is preferable over trying to attempt additional FPS in getting a bullet to stabilize. cold weather will screw a bullet with marginal RPM

The newer Nosler bullets usually get all factory loaded for the cartridge ammo. The two new .277 bullets are 150 regular Accubonds and the 165 LRAB I would guess much later.

I just got through talking in Nosler about the new 165 grain ABLR bullet and they said that the 10:1 twist that we have in stock rifles would not stabilized these bullets. Are your experiences different with heavy bullets?
That's why I went with 1:8" on my .270 AI build in 2012.

"I could fax it easier??"

That statement perplexed me.. until I read

"The OP may be dead by now!"

And then I checked posting dates and it all started to make sense.. lol!
