bigsqueeze - (sorry for the late reply) - My rebarreled and accurized Kimber in .300 WSM which averages 3150 fps muzzle velocity with 180 gn Barnes TSXs has a 25" barrel.
Your shoulder (and eyebrow if you crawl the stock) feels every bit of those 3150 fps when shooting off the bench. Never noticed the recoil when hunting, though.
