The 190's shoot well in my X Bolt, but I could get the the 185 Bergers locally easier than the 190's. I did take a dremel to my magazine so that I could seat them out a little longer, but later that also required cutting out a section of the feedramp in the action.
Seating to original magazine length they would shoot sub MOA no problems with most groups hovering around 3/4, but when I seated them out just a bit further most groups were in the 1/2 MOA range.
I haven't tried the 210's but I'd really like to try some of the 230 Hybrids.
