Obviously 30+ round stages are not representative of real-world encounters for most people, but as you've said, it's a sport. A well-designed 30-round stage is fun and challenging, and that's the point, not how many rounds it is. Honestly, the only reason anyone with 4+ mags on their belt runs out of ammo is extra shots or poorly planned reloads. I've used all of my mags a bunch of times, but ever since I went to 4 mags on the belt + the one in the gun, I've never run out.
No question, the posturing from both sides is pure silliness. Theoretically, we're all adults, but that doesn't mean we're all mature. Find a match near you, check it out, and if the people there suck, find a different one. I was lucky; the first place I went was full of awesome people who helped me learn.2) Comments like "this is where the big boys play". OK Biff, I get it. You are more of a man because you shoot this game vs. another game. Absolutely arrogant, and doesn't sound like someone I want to shoot with. If the other game is so easy, why haven't you won the Nationals, or World championships every year?
Don't worry about it too much at first. You're not going to be in contention to win right away anyway, and after a few matches, especially if you discuss it with the experienced folks there, it'll start to make sense.3) Yes, the scoring seems pretty weird. Note: I say "seems" as a shooter new to the sport.
As PPGMD said, that's club-specific, and of course, your definition of "excessive" may be different from mine, and from PPGMD's and from everybody else's. Again, if a club isn't offering what you want, check out another club. If you're in a major metro area, there should be several options.5) Excessive running on some stages. While I'm not that old and fat that I can't do it, it's not why I want to shoot practical sports. The "track and field with a gun" at times starts to look a bit silly.
Agreed, 100%. I LOVE watching the Open division guys shoot. The speed is insane, the noise is deafening, and the fireballs coming out of the comps are sweet to watch. I would totally shoot open if I could afford it.2) Race guns. I think they are awesome, I don't need to compete with them in production, so I don't mind. They do look a little silly, yet awesome at the same time
