T3x lite barrel profiles

[Ac-13]

Hi all

does anyone have any measurements on the OEM tikka t3x lite barrels? I’m trying to decide between the t3x lite stainless and another t3x lite with D18 barrel profile. I found some measurements on the d18 profile and would love to compare them, see if 1mm of steel will make a difference despite ( or in spite of ) fluting and if it’s worth the 500 dollar price difference… what would you guys do? New barrel here would be around a 1000 easy+ extra government proofing for safety and registration so the buy it cheap and upgrade immediately won’t be an option for the first couple of years …

thanks!
