I see those "tacti-cool" guys here too. Lots of "spray and pray" using copious amounts of now precious, hard to get ammunition rather than focus on precision and technique. Not saying that going through rapid fire exercise can't be fun, but I tend to do it with .22LR which was fairly easy to come by and can't be reloaded. But even then, .22LR can be an excellent teacher of precision. For example, I have a GSG 1911 and it is easy to use, but will really highlight poor technique.
