Help a rookie. This year will be my first time at this event...well, any air gun event for that matter. I have a few questions. 1. Are there limitations on what kind of bench rest can be used? Is a Caldwell Lead Sled permissible? 2. Will AoA be providing air for sale? 3. Will range time be made available to get sighted in before the event? 4. Someone want to give me a hint with .30 cal weight? 44.75 or 50.15 best for the bench rest competition? Thinking heavy for wind but...dunno. Any other advise? I'm driving down from Colorado and should be there the evening of the 5th.
