Well, the new hunter arrived. Too busy to mess with it until next week, but I did verify that my fluted and skeletonized MA bolt fits just like the hunter bolt! That was some cheap (free) weight loss. I assume there are no worries about headspace since the bolt came sealed in a bag, and might never have been affixed to this rifle and fired? I might even be able to rob the stock for my hunt this month and use the hunter as single shot? Then again, I'll just pull the gel and get those weights in time for the hunt. This winter, it will be off for fluting, cerakote, MPI stock etc...
