My hunting partner has lost one, as has another customer of mine last season. It's rare, but it does happen. I know because they both called and asked for spare mags lol
I'm a BDL guy and recommend it to most everyone. Lightweight, doesn't rattle (common with the AICS mags), low profile, and after the first three rounds I can single feed fairly fast if need be. Also, being that I build a lot of long action magnum chambers, I need a 3.85" mag box most of the time (think 28 Nosler with 195's, or 300 Win with 215's with the proper freebore). Only magazine that'll do this is a 5 round AICS single stack Lapua CIP length magazine. Which protrudes about 3" below the stock line, is heavy, and magazines are $80+. I can run a Wyatts box with either a centerfeed or staggerfeed setup on a BDL and have the same magazine length allowance.
If you have to have a DBM, my favorite recommendation is the HS Precision. Centerfeed double stack with a 3.75ish mag length for the long actions, nice compromise between the factory 3.65" boxes and the Wyatts 3.85".
My .02, worth what you paid for it.
