1:10? Are you asking what’s in it or what you should put on it with a new barrel?
The AT LE is a 1:12. Pretty sure the regular are the same.
The UK proofed Barrels are 1:12 and will stabilize the 175 no problem. I shoot 178 Amaxs out of my 20” Uk barrel at about 2535 fps. Zero issues.
Some will tell you scrap the factory barrel because it’s not Bartline or 1:10 or whatever else but I’d shoot it first before thinking you need to replace it. My factory 308 barrel is a lazer.

My factory AT barrel is a 1:12 and loves 175SMKs.
The AI 1:12 hammers with 175s.
