RE: Reminton CDL vs. Browning A-Bolt Medallion
The difference in "feel" between the XCR and CDL may be the width of the top of the comb, the CDL being a tad bit wider than the XCR.
Also the XCR, being lighter in all the wrong places lends itself to being slightly barrel heavy, an unpleasent feeling.
True there is more aftermarket upgrades for a Remington, however try not to buy a rifle on this asset, unless you intend to spend extra dollars in this arena.
The CDL's weigh in at around 8+ pounds, after a scope, mounts, sling and ammo the CDL can push 10 to 12 lbs.
The A-Bolt the same.
Any one of the mentioned rifles are excellent for what your after, Remingtons are good; the Brownings also... the Savages tend to be a bit more accurate than the other two( I bet I catch crap for that... but it's true) so long as the Remington is a "new" one, the older Remingtons were accurate.
I guess what I'm saying is try them all on and see which one likes you the best!
