If one was to convert from 7mm Rem Mag to 7mm Dakota, what would they have to do? I believe both are same action length...correct? So simply rebarreling could nearly do it. The little information I have lists the 7mm Dakota headsize at .545 where as the 7mm RM has a head size of .532, so I would have to open up the bolt face by .013 in, correct? How big of a procedure is this? I have a Rem M700 BDL with a Sako extractor, if it matters. Also, any experience with the cartridge? I would like to push a 160 gr bullet @ 3100 fps from a 24" barrel if at all possible. Know of a place I can get brass? I'd like reload data with cartridge specs and an honest answer as to whether or not it would be worth the conversion. Thanks for any info...
i would think it would be a rechamber for you. if you wanted to rebarrel anyway it would be cheaper to go the RUM in 7mm i think. brass etc and you would reach your velocity goal....... woofer

I've tried a .404 Jeffrey case, ~.545 rim dia., in a bunch of Remington "magnum" bolts and all of them accepted the case. With the Sako, it should be simple to open the snout a bit if needed. The Dakota has less cap. than the Ultrmags. The .330 Dakota brass is quite heavy, European manuf., but I don't know the source for the 7mm Dakota brass.
