Yes, Remingtons taper steeply to a point about 13" ahead of the receiver and then are a straight tube to the muzzle. They have very little actual straight shank. A better example would be something like a Ruger Hawkeye which runs around .575" with a more standard shaped contour.

But the point being that a #2 contour like the MRC makes for a good balance on a sporter weight rifle, especially with a 22" length.

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
