Free Advice (worth what it costs?)
Many Trap shooters are quite willing to give advice and "lessons", if asked.
The nice thing about this is that you'll often get completely different advice from different shooters, so you'll never be bored!
IMHO: Most importantly, find a gun that fits - it's easier to do in person than describe, so ask a few friendly Trap shooters if they'll let you try theirs on for size. An inexpensive gun that fits you will work better than an expensive one that doesn't!
Best thing to do is watch a couple of rounds, and see what the shooters who break the most birds do. This is a good starting point.
Another very important point: there is only ONE bird - don't think about the one you just hit ( or missed) or how the other shooters are doing - just get the gun in the right position, call for the ONE bird, and let nature take its course.
This past weekend, my nephew brought his friend out to our Club, and after a breif explanation of the game (and a safety breifing - he'd never shot before), and a couple of rounds to "warm up", managed 18/25. Not too shabby!
OH, yeah......have fun!
