I've used both Winchester 70 (new CRF) that worked swell and Kimber 8400 ("almost CRF?) in 300WSM that fed very well. Remington 700 SA had to be tweaked a bit to feed OK, still pretty rough. Great round though, I stuck with Barnes 168 TSX and later 168 TTSX. R17 was King! I don't own one now as I have a soft spot in my heart for the 300WM, its Old Faithful to me. smile
