Yep. I have Ridgelines in 6.5 Creedmoor and 300 Win Mag. Love them. Both shoot 1/2"-3/4" 5 shot groups at 100 yds. I don't care much for the factory stocks, but that's personal preference. I put them both in McMillan Game Wardens.
Sorry for the high-jack, but what is your load in the Ridgeline 300wm? Working a load up for one now. Dumped the stock for a XLR chassis also.
