A lot of shooters at our Appleseeds (Kansas) shoot rimfire on Saturday, and centerfire on Sunday....
We're about to get a KD (known distance) range going, where we'll be able to shoot to at least 500 yards, possibly to 1000. I've never shot over 300 yards, so I'm looking forward to this!
You're right about centerfire ammo, though....when I'm shooting my Garand, there is a LOT more concentration taking place than when shooting a .22...
