I know all about the theory, which is why I asked for personal real-world experience from those who own some of the same caliber in 22-inch "normal" rifles, and the 26 and 28 inch single shot rifles.
I was thinking about the Ruger No. 1B, and the 1885 High Walls, but it would apply to bolt actions, too.
For example, I had a 26-inch .308 Steyr SSG which got about 150 more FPS out of a 173-gr bullet, and 100 FPS more out of 150-gr loads.
My Model 70 single shot in .30-06 with a 30-inch barrel would push 190-gr and 200-gr bullets 150 FPS faster than my 22-inch Model 70 or my Remington 700.
That's what I was looking for - the people who own, say, a Ruger No. 1-A and a 1-B, both in .270 Win or .257 Roberts.
