The game can be as easy or as difficult as you want to make it. Shoot from bipod, bags, rested or from full on gyro-stabilized, Lazer guided table top installation. You are truly competing against the score card and the wind. Everyone shoots in the same conditions. I am too far from perfection to worry about it, so I am focused on incremental improvement.
The N50 is designed to allow for Airguns and .22lr to shoot head to head. The first year, and airgun beat all the .22lr.
I don't have a Lamborghini gun, rather I haul my Walmart hunting guns to the table and do my best. A PCP with 25+ foot pounds will do you ok. I have portable pumps and an air tank for refills at the range for the pellet guns, and .22 ammo for the Ruger.
You can download a practice target to print from your computer (get the left and the right side, both!). I will be happy to send you some competition targets, too. The higher density card stock makes for better holes for score keeping.
