I shot the 195 DC in a Traditions Lightning LD with 100gr FFg 777. I got 2000fps on the nose, MOA but groups blew up even at 105gr so I stayed at 100.

That was the only gun I have ever sold, 30min+ to clean (full bolt disassembly, firing pin wore out in 2 yrs). I got my first Omega and it would not shoot any DC bullet at any reasonable (ie 90gr+) charge so I haven't shot them much in a few years...though I have taken a couple deer with my old sidelock as a backup gun shooting the 300gr Keith Nose HP.
