    I've all but decided on re-barreling my .308 AI-AWP to .260 Remington, and I'm curious as to just how much velocity I stand to gain going with a 26" barrel over a 24" barrel.

    Has anyone performed (or know of any) chrono testing starting with a 26" (or even 28" or 30") barrel in .260 Remington then cutting off an inch at a time to see the impact of barrel length on velocity with .260 Remington? Is there any reason it would be significantly different than the expected difference with .308?

    I don't know of anyone.

    It should be a little more per inch than .308 because it's more overbore.

    I would expect 35-65 fps difference 24 to 26"

    Jeez, Zak...it took you almost a full minute to respond. You're slacking... :)

    Thanks for the reply! I'll probably just go with a 26" barrel and wait. I'm not even sure if the factory AI barrel will even be chambered in .260 Remington or just a .264 caliber that still needs to be chambered (waiting to hear back from AI).
