I converted my 700MLS to 209 a few years ago with the cabela's one. It has worked excellent. I know a number of guys who have experienced problems with the rem 209 kit and the ones that have switched to the Cabela's are now thrilled!

I use winchester 209W primers and haven't experienced any problems with hangs, misfires or the dreaded crud ring using T7 Loose.(I do swab between shots though and my current load is 100 grs loose)
