I've killed a lot of deer in my 60 years of life. From .221 to .300 WBY, they all worked well if the shot placement was right. My current deer battery is a 7mm/08 and a 6.5x55. I've shot some big deer in the past 6-7 years with these two rifles and I'm sure the deer couldn't tell the difference, all piled up pretty hard in the results.
I have found I actually enjoy shooting these lighter recoiling rifles all year round, which in turn, helps my shooting ability come hunting season. I sold my ultra-lite .300 Weatherby many years ago and do not miss it!
But not to totally hijack Pete's thread ... the Ruger does look interesting for sure. But Pete, if you're going to dabble in long range shooting, get a caliber that's recoil tolerable to YOU, and don't worry about what everyone else is shooting. Take baby steps in distance as well.
Long distance is in the eye of the beholder, and his/her ability as well. Whether 100 yards or 300 or 600, etc., can all feel good when you consistently punch that bullseye.
