[QUOTE="Buttermilk, post: 1053717, member: 5262"] 8-8.5# without scope means no bigger than a #3B Bartlein most likely. Perhaps even a #3 Bartlein contour. I'd have to look and see what that corresponds to for other manufacturers contours. Fluting would save a few ounces at most. In the 300 RUM, I'd strongly consider a 9" twist for running the heavies like a Berger 230gr., though a 10" twist would work. There are other bullet choices like a GS Custom bullet, for example, that would benefit from a faster twist. [/QUOTE]
