My biggest gripe about external box (DBM) magazines are about 80 percent of them don't work.

We see shooter after shooter after shooter on the firing line at our matches with "tacti-cool" rifles with those type mags hanging up. The guy has to fiddle with the bolt... drop the box out of the action, fiddle with that a bit... smack it a time or two... reinsert it, then try again.

The most reliable feeding design for a bolt action rifle, in my opinion, remains the rotary magazine design.

I have a 1937 Mannlicher-Schoenauer rifle with a rotary magazine and it is 100 percent reliable.

Also, take a pre-64 Model 70 Winchester... 100 percent feed reliable.

As to newer model, commonly available rifles, Savage's "center feed" mags work pretty well, from what I'm seeing.

But unless that box mag is done right, by someone who really knows what he's doing... I wouldn't put much faith in it.
