thinking about doing a 7wsm build and ive been seeing a lot of guys using the badger ordnance m5 dbm. i havent actually seen one for a wsm so im assuming its the short action gaurd but what mags are you using?
Something else to consider would be the Seekins WSM DBM assembly. They offer an internal mag length of 3.14" so you will have no issues with nearly any bullet you wish to shoot. A slight modification is needed to the bottom of some actions but could be justified if you need it for long bullets.
I have a Seekins set up on my 7wsm and it operates nicely. My smith did the modifications to my action so that I am able to load what I want. The freebore wasnt cut to an extreame length as I had it set up for the 162 A-max. I'm at the lands at 2.95 COAL which works out pretty good with room to spare in the magazine. It's a great set-up for the short action and the mag release is very comfortable especially when switching from an AR platform.
