Hi, I recently purchased a brand new Rem XCR II in 375 H&H for an Alaskan brown bear hunt this fall that had some issues right out of the box. The extractor was a bit too large so it chambered factory rounds very hard, so I took it to my local and excellent gunsmith, Kevin Weaver, and am having it worked over (good thing I got it cheap!). He replaced the extractor with a Sako extractor, welded the bolt handle on, and I had him rechamber it to 375 Weatherby. I should get it back this weekend. 300g Nosler Partitions at 2800 fps from a 7 3/8 lb rifle (that includes scope!) should be fun. Recoil as a 375 H&H was mild so the 375 Weatherby should only be about 10% more recoil.
