Meh. Going to the range and practicing is trying. I'm not in the habit of giving unsolicited advice, but I've been asked for pointers more than once just being friendly (vs. taking pictures of their target). Lessons might be better, but repetition helps IMO.Not really, at least the fat people are trying.
90% of people at indoor ranges shoot like that or worse. As long as they're being safe, following the rules (speaking of which - aren't cell phones banned on the range at Cindy's?) and don't reek of pot smoke, I find them far less annoying than the fudds who want to appoint themselves RSO and call range cold every 5 minutes to measure their 3-shot group they shot over 20lbs of sandbags.
