I have a couple of pretty accurate 270s, a CLR and a Husqvarna built S&W Model A, that I have only shot factory ammo in. I haven't shot either one a lot, but found the 130 grain Winchester/Olin Power Max Bonded and Hornady American Whitetail to be MOAish. I am particularly pleased with the 300+/- rounds of Hornady factory ammo that I've shot in the 6.5 Creedmoor and the 40 shot just today in an RAR Predator in 204 Ruger.

I don't know if I'll set up to reload for the 270s, as I just don't see myself shooting that cartridge enough to spend the time working up more accurate loads, but time will tell.
