Well, I don't have an M24 contour here, but have the 5r & 2 or 3 factory Rem varmint contours & a couple Kriegers that were advertised as so. The 5r is a tic fatter, or memory says it is. I'll check tomorrow.

Mathman, does your 5r group like a decent custom build? Mine is the most or second most accurate factory rifle I've owned(11.25 twist). 175 Match Kings over a medium load of Varget in Lapua cases make me look like I know what I'm doing.
