[QUOTE="Lefty7mmstw, post: 809210, member: 48043"] I have a feeling that you are right on the 7rum possibly having better bbl. life with a shorter throat. You will run into the same issues as some of the roy rounds though, in the fact that factory loads and book loading data may cause over-pressure situations at times with non standard throats. I also think the already small velocity gap may disappear to the point that the 7rum is basically just a less efficient version of the 7stw. All this talking about the 7rum and I haven't had one in a few years now. The caliber's calling my name pretty loud lately. A 27-28" 10" twist 7rum throated to 3.8" would smoke a 140 ab pretty well for mule deer way out there. I'll built the 7rum as a right hand heavy bbl and leave my 7stw as a left hand carry rifle. Now where's the cash fairy so I can get this done by hunting season???:D [/QUOTE]
