If last year was any indication, there ought to plenty of firearms to shoot.
Cramming the schedule with daily shooting events helped raise people's awareness to the fact that there is an adequate free shooting range just down the road from the campsite, and so many people expressed enthusiastic interest in bringing firearms to PF'06.
Unless you have something special to bring, I would recommend saving any money involved in transporting, transferring, or purchasing firearms for targets, ammunition, and incidentals (target stands, tape, staples, etc) once you get there.

If anyone has a shot timer, chronograph, or any other specialty equipment, please bring it along!
The majority of shooting events are informal, so if you have a shooting event that you'd like to run, PLEASE contact me or the PF'06 event planners to tell them so! We can use as many people to coordinate events, procure equipment (targets, stands, ammo), give rides, give instruction, and act as Range Safety Officers as possible!
