B-run,
I also enjoy bagging on the "Tacticool" guys. Nice to see we agree on something.

There are also the guys that I refer to as FUDD gunners (as in Elmer Fudd). These guys only fire two or three rounds a year in practice, hit the paper plate set up at 25 yards, and call it good.
I usually shoot 500 to a thousand rounds a year, in different rifles and handguns, so that when the shot arises I'll be able to hit my mark. Usually I'll get out 2 or 3 days a month to practice, sometimes more.
The 30 round mags don't work so well at the bench and the woods, because of their length, so I tend to gravitate to the 10 and 20 rounders. The 10 rounders (.223/5.56) will hold only 3 rounds of my .458 SOCOM, so while it looks large, its just because the round is so large that it stacks single file instead of staggered like a .223 round. Some folks will even go so far as to take a proven reliable mag and insert a pop rivet to limit the number of rounds the mag can hold for hunting.
Heck, I can even get a 20 round mag for my Remingtion 740 auto-loader, if I want, but I'm happy with the 4 rounders I have. I did switch out the wood stock to plastic, as I hunt in the rain, and the old stock my grampa had on it was dinged, scratched, cracked and dented.
