Is there any standard production 7mm Rem Mag. bolt rifles with an action long enough to accommodate the STW cartridge, and if so, will the STW fit in the magazine? In other words, can the Rem. Mag. simply be rechambered to the STW and your done? I think I saw one the other day. The " Mag. " part of the factory barrel stamp was marked out and STW was hand stamped next to it. It read, 7MM REM. XXXX STW on the barrel. I've never owned a 7mm mag. but thought the whole reason the Rem. mag. casing was 2.5" was to fit the standard long action like the 30/06. and I also thought the STW cartridge took a magnum length action. So I guess I'm getting ready to get schooled on those thoughts aren't I. Thank you for your time, Tim.
