Angus - 5024, shoot the rifle first before you ream it. You might like the way the rifle shoots. I have one of this XCR in 300 WSM and I'm very disappointed. First to start with I could not install the one piece Leupold mount. The holes are not space the same as the holes on the mount. The deference between the second and third holes are like .018" and trust me, that is to much to start the screws. Then I install a 2 piece mount on it and a Leupold VXII scope to go with it and out to the range. Best I got 3.5" groups at 100 yards.
Funny because all I wanted is a reliable hunting rifle that can be safe to shoot out to 250-300 yards. Originally I was going to get the Tikka T3 SS 300 WSM, but during Christmas it sold out here in California. I could not find one so I decided to buy this XCR and boy I'm disappointed. I figured an additional 300 bucks and help the US Firearm makers, boy i shot my foot. I'm wondering if Remington is a Union shop.
I have some pictures loaded on my website, hopefully someone can tell if the carbon on the casing is normal. It only build up on one side of the neck. I do not think a 1.25 or even a 1.5 MOA is to much to ask for a $900 factory hunting rifle. So, shoot it first and you just might be happy to ream it out. I would with mine . www.gottrikes.com/XCR300WSM.htm
