I own a 6.5 and 7.7, the 7.7 was sporterised when I bought it, the 6.5 I sporterised myself. both shoot great especially the 6.5, I have shot groups as small as an inch with handloads. A few years back at a gun show I bought 7 boxes of once fired Norma brass for forty bucks. If you reload your own ammo and have access to brass at a reasonable price I see no reason to spend the money for a rebarrel job.
