Never owned the older XCRs, but the new one(type 3)keymod shoots well(I coyote hunt with it). Has a nice balance. I have only shot reasonably fast at targets(5 rounds, walk down, check target, walk back, insert new mag, and send 5 more). I've not seen an issue with the pencil barreled model I have. I did tune a coyote's cruise control up that I jumped with a mag beginning at about 100m all the way out to 250m yds
It's light enough to hump around the farms with 2 mags, in shin deep snow along with a pack full of hand calls, e caller, water, snacks, folding stool/pad, etc. However I'll darn sure use snowshoes next time, but not because of the xcr weight.
A 6.8 or 7.62x39 will likely be in my future.
