Not only does it cause frustration with the shooter that was told he couldn't shoot until Saturday, but it also puts a burden on the groups that had to shoot the same ranges as the Pro's and Semi-pro's. Pro's and Semi-Pro's don't have to follow the 2 minute rule like the amatures, so we have to wait 30 minutes behind 2 groups of Pro's on Sunday with 20 targets to shoot before 1:00. We finished the 10 target range at 11:30, then they had to drive all the way over to the other ranges 2 miles away and try to finish by 1:00. This stinks. Need some rule changes or let the Pro's / Semi Pro's shoot their own ranges. I like IBO compared to ASA simply because of the freedom to shoot 10 at a time or all 40 if I want to, but you can't shoot 40 targets in 6 hours if you have to walk 2 miles on each 10 target range and drive 2 miles and shoot behind the Pro's / Semi Pro's.
