It really depends on the event. The Findlay Cup, held on Sunday, is an individual event and always has been. It's a little less 'high-speed-low-drag' than some tactical events, though. Usually we have a group of cowboys who bring their coyote rifles and lay out their saddle blankets to shoot off of
A gun with a box mag is definitely a plus... although again, it depends on how the course of fire is laid out. Ours tend to be pretty laid back, though the time limits were tightened up. It's possible to feed the first 4-5 from the mag, and then single load (assuming you're proficient at it) thereafter and keep up okay. I'm ordering a couple 10rd mags for my AICS 1.5 stock, though. Better to have and not need than need and not have, as the saying goes. I wouldn't let the lack of a DBM keep me home, though. Stock packs to hold extra rounds, hell even pockets work just fine. Might not win, but you'll still have fun!
The WCT event was a team affair... depending on the stage, the 'shooter' would handle the long shots and the 'spotter' the pistol or carbine portion, but on some stages both people had to engage all the targets - strong side *and* weak side, which makes life... interesting. If you think it sounds easy, try it some time ;)
The Hummer stage had one shooter engage some steel targets at distance, and then the other person was in the back of a Hummer w/ an AK-47 (gun and ammo provided, so everybody got the same advantages/disadvantages) and had to engage some stationary steel half-size silhouette targets from the back of the Hummer as it drove along. Three shots from port, then the vehicle turned around and came back, and three more shots from starboard.
Apparently it's pretty damn hard to hit something from a moving vehicle without a belt-fed (or at least high-cap) weapon with a selector switch - I think only a couple people hit 2 out of 6 of the carbine shots from the Hummer. A few hit one, and a whole bunch hit none.
The Night Poacher stage was pretty fun... two minutes for two shots each shooter and spotter, at a target ~512yds away up on a hill side. Some reflective tape (simulating 'eyes') was about 8-10" above the steel swinger target. RO held the spotlight on the reflective tape, and the shooter/spotter had at it. Very cool. You could tell who has spent some time spotlighting coyotes by looking at the scores!
Surprisingly enough, nobody was brave enough to attempt the 100pt circle on the Know-Your-Limit target
I think one or two guys did get the 50pt circle. A surprising number missed the 2" 5pt circle... and these are guys who generally shoot pretty regularly, have good gear, and more or less know what they are doing. Match nerves will do that to ya, though ;)
