[QUOTE="shortgrass, post: 1199085, member: 24284"] And the next thread will be, "Help! The cartridges won't feed/stay in the magazine!". I don't believe I've converted a rifle from 300RUM to 300 Win. Mag. , but I've done quit a few the other way around. Going from Win Mag (or 7mm Rem Mag) to 300RUM has always required a bit of work to the feed rails and ramp, and a bit of tweaking to the mag box lips (on a 700). With the availability of new Rem 700 actions, I've noticed there's a seperate magnum action listed as an "Ultra Mag" action. There's a difference somewhere. I'd suspect in the feed related areas. I can tweak the lips on a mag box, but there's not much I can do if the feed rails and/or feed ramp are too wide. As for questions about bolt face diameters, JEs' sticky is a very good one, and if ya' need more in formation the Sporting Arms & Ammunition Manufactures web site should be consulted where industry standards and tolerances to be found. Da*%! Heres another link: [URL="http://www.saami.org"]www.saami.org[/URL] This is the "final word". It supersedes any dimentions found in loading manuals for industry standard cartridges (not wildcats). [/QUOTE]
