So I own a RSI in 30-'06. It shoots quite well and I've had a couple small things done to it. I'm thinking of having a 260 Rem or 7-08 barrel put on replacing the '06. Question: where do I get a quality barrel and which caliber is best in a 20" tube? Only reason for the second half of the question is I recall a few years back there being some talk about the 260 performing poorly out of short barrels.
