lancetkenyon Report post Posted December 30, 2015 .300 WM case length 2.620" SAAMI COAL 3.340" .300 Norma Mag case length 2.559" SAAMI COAL 3.346" .300 RUM case length 2.850" SAAMI COAL 3.600" I doubt .006" would hinder the Norma Mag from fitting in anything a .300WM won't fit in. I know I seat my .300RUM out to a COAL of 3.680" and it fits in the mag still with room to spare. Share this post Link to post Share on other sites
