RE: Opinions on the Remington 700 XCR
Your caliber selection will take you an awfully long way. Though there may be better choices for each of the species you've listed, there's not likely a better choice for the group.
Aside from the stock & the TriNyte, I'm not sure how the XCR is different from the SPS SS. You may want to handle both to see if the $250 to$300 price difference is worth it to you. I've never hadeitherkind (SS or TriNyte) of rifle, so I don't know how well they stand up to the elements. If the SPS SS held up well enough, you could save some $$$, & still have a reat shooter.
FWIW, I settled on the CDL in .30-06, and I love it. Had I not been such a blued-steel-and-wood-stock kind o' guy, I'd probably have gone with one of your choices!
Good Luck,
