Wonder why I can' t find a manufacturer that sells a 300 UM w/ detachable mag? Browning, nope. Rem., nope.

I really wish Rem. would make one. The 700 BDL DM, stainless, with syn. stock (camo please). I imagine due to the length of the cartridge it may not be feasible so my only choice seems to be a 300 WSM from Browning. I' d even settle for a Rem. 300 SAUM but they don' t seem to offer much of their line with a det. mag.

Anyone else have some recommendations on how to get my dream gun? Am I the only one that really likes to carry a spare mag. while out hunting?
