I was gonna go 6.5 but changed my mind.I've narrowed it down to either the Shilen .750 with matched bolt or the RRA 1.050 under the handguard to .936.The RRA is around $290 with gas block and the Shilen At $419 .I don't mind spending the extra cash but it would be a plus not to.Both are 20" 1/8 wylde .Using it out to 600 max for target and closer for predator hunting and pdogs.Shilen states it's a match grade barrel and I'm not sure if the RRA is.Which one would you get and why?Thanks
