[QUOTE="MudRunner2005, post: 1322100, member: 12995"] You will have to have it rebarreled with a proper 1:8 twist 26"-28" barrel (I recommend the Bartlein 5R 1:8 28" Rem Varmint/Sendero) to push the big heavy high-BC long range bullets like the Berger 180 Hybrids and 195 Elite Hunters. You cannot rechamber that factory barrel without cutting an inch or better off the chamber-end (tennon) that's threaded, because the .28 Nosler is a much shorter case than the 7mm RUM. Might as well just have a new and proper barrel blank chambered for .28 Nosler and installed onto your action. If you do that, it will be a very simple process. Remove the old barrel, blueprint the action. Then thread the new barrel blank and set the shoulder for the lug, chamber the new barrel blank, headspace the chamber to your action, install the new barrel. That simple. :cool: [/QUOTE]
