After many seasons with the BDLs and wood stocks when was young and that was all we had, I added a DBM and synthetic stainless. That was many years ago. I would never go back to the BDL or wood.
The Rem DBM system is flush and nearly impossible to have one come out by accident because it has two independent release tabs that you must squeeze to pull the mag. No accidental bump or brush is going to pull it out, nor will recoil. In the long action, they have a good capacity, four rounds in .30-06 sized cartridges for example.
Pulling the mag out for legal reasons on vehicles is only one reason to work with DBM. Carrying the extra ammo in the spare mags is another. How many minutes have been wasted when friends spill rounds on the tailgate in the dark and we have to find them on the ground, gate, or bumper at night?... A mag insertion with a gloved hand is easy even with cold hands. Loading or dumping a BDL when your fingers barely move isn't as quick or quiet.
In the end, it is good to have choices. ADL, BDL, or DBM, is a personal choice, not a law of physics. YMMV
The biggest issue I have now is waiting for Remington to start making the bottom metal again for a new build. They stopped when they got into trouble and have not said when this DBM design will be available again.
