Blind Magazine Box help

Hey guys,
Im working on taking my Savage 11 Hog hunter 223 and putting a Savage 11 22-250 barrel on it. Got the 22-250 barrel threaded, found a splined barrel nut off one of my older savage 30-06 barrels along with the bolt head.

Now im in the search for a center feed 308/243/22-250 blind magazine box along with the follower.

Any idea where to start?

All my searches come up with the detachable magazines that i dont need.


Thanks

A detachable magazine will work, you'd just pop the bottom plate off to use it in a blind mag configuration. Axis or Trophy Hunter style would be cheapest, but still probably a little more expensive than just buying the individual parts direct from Savage.
