PrarieBoy,
With my Rem. Mtn rifle I could reel off five shots from the bench before the barrel heated up. I never noticed too much impact shift while load testing, it shot about the same cool or hot. One thing to think about , thin barrel heats up fast and cools off fast. IMHO the Mtn rifle is one nice piece of equipment.
Also something to think about if you are shooting in cold ambient temps barrel heating usually isn't a problem. Most of my shooting was in ambient temps between 40-90F.
