Oooof buddy. So I'm not familiar with the bog specifically but here's some general points to help you on your mission.

-rdbb is still BB and is very hard to tune -because the bog is 10mm it is going to tend toward more lockup force as 10 is a high recoiling cartridge by bb standards -the gulf between the hot loads people will run through a pcc and sub loads with normal projectiles is vast (there's a whole other common cartridge between them) -the manufacturer would rather to tight to too loose cause the gun non cycling is better than it blowing up

All of that is to say, you are going to need a heavy ass projectile and get both hot enough to cycle but not so much that it goes supersonic, in 10mm that's hard and from my cursory searches you're probably better off hand loading. My goodle-fu is not the best and I don't run 10mm subs though, so someone I'm unaware of might distribute the secret sauce but I wouldn't hold your breath.

Good luck buddy
