I have three recent purchases and considered the S&W, but finally went with the Ruger AR-556, because my local chain store had one with all the mods I wanted already installed (except a Timney trigger). I have a Savage Axis in 6.5 Creedmoor, a Remington 700 in 7mm, and the Ruger. My favorite is the Savage, even thought the 7mm absolutely blows it out of the water for range. I can hit up to 900 yards with the Ruger, 1,400 with the savage, and 2,000 with the Remington. Probably the glass makes all the difference, though. I use Leupold on all of the above, but recently bought an ancient Unertl 25 power and mounted it to the Remington.
All of the above I reload with Lapua brass, Berger bullets, and CCI Primers, but I never found a powder that was common to all three cartridges.
This coming Fall, if the travel quarantine is lifted, I will be hunting Dall and Elk. All year round I do coyote hunts by request of the stock owners (cattle), so my intention is to suppress the Ruger at some point. The, or maybe I'll just go with a Daniel Defense, or Wilson Combat model with their proprietary suppressor.
This hobby is getting to be really popular with the preppers, and supplies can be hard to acquire!
