Have a bit of range time with a T3 Lite in 300 WSM. Definitely needed a Limbsaver recoil pad, fairly sharp bite to it. I don't think 22.5" barrel will affect ballistics in any way that a deer, elk or moose would notice. Nor do I think one would notice the difference in muzzle blast.
Keep in mind, recoil can be significantly reduced with lighter bullets, in this case going with 150 gr instead of 180s. With quality bullets, bonded or monolithic, will get the job done just fine on N.American critters, save perhaps for stopping an oncoming griz.
