[QUOTE="MontanaRifleman, post: 273588, member: 11717"] There have recently been a few threads discussing the short barrel life of some of the overbore cartridges... especially the Ultras. So I was wondering if we could get a little survey on the subject. What has been your experience with barrel life? And give some details like how hot your loads were... cleaning regiments... did you notice a change in performance? etc... I have only ever shot out one barrel and that was a Ruger M77 7mm RM CM factory barrel, after about 1000 rounds. Took it for a bore scope after it started loosing accuracy and the throat was toasted. I shot mostly "warm" handloads from it as well as some factory stuff and cleaned it with Hoppes powder slovent only. Never cleaned it with a copper solvent until I cleaned it with wipeout after it was toasted. When I decide to go with the 300 RUM, I figured it would last about 1000 rounds or maybe a little longer. I was also considering the 7 RUM which I got the impression from different posts would give a barrel life of about 1000 rounds. So if the 7 could get 1000, I figured a 300 could probably get a little more. So let's hear your experiences and it doesn't just have to be the overbore cartridges. [/QUOTE]
