Questor - that kind of stuff drives me nuts and I have had to tell more than one person to stay behind the firing line until I was through with my string. Some think that just because you are shooting on one target at 100 yds they can go downrange and check their targets while you're still shooting. One guy told me - hey, you're hittin' the paper, what do I have to worry about......... Here's your sign buddy!
And yes, we older retired guys are a pain - too much time to bs on the range. Fire a couple of shots, check the target, bs a bunch, fire a couple of more shots, bs about the last operation, teh kids, the grandkids, the dog, the wife, etc. The trick is that most retired guys don't usually get to the range before 11 or 12 (we often sleep in, lol) and I try and get there a bit earlier so I don't have to deal with the holdups. It's a trip, fer shor, but it's still shootin'. Mikey.
