[QUOTE="IdahoCTD, post: 620507, member: 13110"] Remingtons use 1 magazine length and 1 action length for all long action cartridges including 7rm and all the RUM's. The mag. box length is 3.68" long. Short magnum actions only happen in Mausers, Ruger, and a few others. Remington only makes the 700 model in 2 lengths, short and long. Go look at magazine box lengths or stock options on Midway or any other site if you dont believe me. The RUM cases are actually bigger (.550) then a standard magnum belt which is .532. Remington also makes a .338 Lapua in their standard long action which has a .588 bolt face diameter so rechambering to a .550 case is no big deal. BTW the .375 Ruger is the same diameter as the belt on magnum cases (.532). Personally if it was me I wouldn't go bigger than a 7STW or 7mm Dakota. The 7RUM really needs a longer barrel then 26" to outpace the STW/Dakota by a decent margin and it would result in shorter barrel life. Also cases cost more, when you can find them, and you burn more powder (ie less barrel life). [/QUOTE]
