I am curious as to the validity of your remark. I've met many first time event shooters at RMAC, mostly in the Sportsman class. But, a prime example of a 1st time Pro Class shooter is Dusty Powers, winner of the 100y event. He wasn't part of any team, he wasn't part of the airgun industry, and he doesn't do any Youtube or SM (besides a private FB page).
Most people start shooting in Sportsman class and work their way up to Pro class. If you win an event as a Sportsman, you're actually forced to shoot in Pro class after that.
Registration is open to everyone, but just like EBR... you better be on your computer and ready to register when the gates open!
If you were determined to get in to the event, and failed... we'd love to hear your story in full detail.
