The Trophy Hunter's use the Axis style detachable magazine. Unfortunately, if you're wanting to get a Boyds stock it doesn't look like they currently have the right option in their drop-down menu system for your rifle. They have the Model 111 Trophy Hunter Bottom Bolt Release, but not the Model 11. Maybe calls Boyds on this as given how many Model 11 Trophy Hunters Savage sells every year I'm sure they have a program for it and it was just an oversight that it's not in the website menu.

The Model 11 Bottom Bolt Release won't work because it's inlet for the higher end detachable magazine with separate bottom metal.
