As far as I know, no one has the COF, so there should not be an advantage in that regard.
I am waiting for a round count, need to stock up, and ammo seems to be getting harder to find lately.
Depends on your mag capacity and division. For tac optics, probably less than 40 rounds handgun and 60 rifle per stage, but extras would be good. For instance, reload strategy may suggest dumping a partially full mag, and always have a spare. Shotgun, probably no more than 30 birdshot per stage, but could be less than that. Remember, super high round count per stage would mean more taping and reseting which slows down the match, and we want to keep things moving.
It may look like some have fore knowledge but a lot of us have way more ammo carriers and mags and ammo than any one person should, so we just bring it all and LOOK prepared. Also, shooting the monthly matches at BOTW means we get kindof a preview because the stages get tried in a fashion so there are fewer surprises when the match starts.
Alden, as for stocking up on ammo - buy it now; you know you are going to shoot it anyway.

Lee, you've shot WW2 division in a monthly match, if I remember correctly. If so (?), do you have any tips you would be willing to share with others that might be shooting in that division for the first time?
