Please, no one get the wrong idea, because if someone gets one of these new 3000fps rimfires, count me first in line to give it a try!!
I just don't understand all the growing interest in all the new rimfires. For sure they are all just plain fun to shoot, including my own old .22 Mag. I just feel like it is a big advantage to be able buy ammo or reload it yourself. A number of small cases necked to .14, .17 or .20 would make some really cool 3000fps cartridges.
