If you can't find exactly what you want: Ruger has done a special run of their American Predator rifles chambered in 6mm Remington (not Creedmoor). 22" semi-heavy barrel, dbm, adj. trigger, etc.
I've been swapping out my .243s for 6mm Rems.; at well-under 500 bucks I can live with the plastic stock for now.
Good luck, they're definitely out there and I think alot of people are caught up in the newest, latest, greatest caliber craze. I just snagged an older BDL on arfcom for a good price. Mounted a vx II 3-9x40 and dropped the barreled action into a bansner stock. My only regret is deer season is already over in VA and I have to wait until next season to whack some deer with it.
