Thinking on the purpose of the three rounds. Having gotten out of to pretty firearms, i try to have each firearm have a specific purpose. So what would a purpose be for 17/22mag that another....22lr, 22 hornet, 204r, or 223 not do better. I am not saying that there is not a answer. I dont know your individual uses. IMO at the range the 22lr is my rifle i shoot to slow me down on my centerfires, the others are just more expensive versions fo the same. Would i use either in a varmit role if i had one of the above centerfires handy? I doubt it.
