I have done lotta research on 375 h&h rifles, I seattled on the winchester classic stainless (I have 2 of them in same caliber), they shoot very well.... but like you said, those are kind of expensive nowadays...
I personally like stainless steel more than blue. As far as which rifle you want and Even though the a-bolt is sweet, but there is something about those remington XCRs that brings me to them more......regarding the XCR's weight, don't be fooled with what the internet label says, they weight around 8.5 lbs without a scope.
You should get the XCR, it will shoot JUST AS WELL AS THE A-BOLT (I don't care what anyone says, they shoot well), and save your self around $200, and you can take that $200, add a little more to it, and invest in a really nice scope (god knows, 375 h&h needs a recoil-handeling scope)....but thats just my opinion
