I have been thinking of getting a .22 mag and a .17 hmr to play with and if i get the ruger i can use the .22 mag action with the .17 barrel also, have any of you done this and is the accuracy good? If i go this route i am going to purchase bull barrels in both calibers and maybe a thumbhole stock. I would be primarily using this to target shoot, occassional predator, and for a prairie dog gun. Is it very easy to switch the barrels back and forth? All i really need to find is .22 mag action since i will be replacing the factory barrel and stock, any good place to locate a action? thanks for the help
