I hope you have a LOT of patience. I shot Bullseye once, that was enough for me. Too long and drawn-out, I like a quicker pace.
Now, it is a very interesting competition. It almost reminded me of my old slot car days. Guys have these special boxes with all their gear in it. Set it up next to them in their lane. In the top of the box they have a spotting scope. They take a shot, look through the scope, see where they hit, get ready for the next. At 25 yards a .22 is hard to see. Yes, the good guys use custom-built .22's. The grips are replaced by a piece of wood custom-carved to fit their hand perfectly!
Some of these shooters are awesome to say the least. Mid to high 800's all the time. Sometimes 880-890, 900 being perfect.
Saw one guy using .45 wadcutters. Easy to score his hits!
I was using .38 special from a 686. Iron sites, heavy gun, no spotting scope, scored bad, but it was an experience. Think I shot a whopping 410 or so....
Hey, give it a shot and see if it's something you like. Next to shotgun sports my next favorite is knock down steel. To each their own, have fun!
