I believe Franklin Armory makes an AR15 type .17WSM that is an absolute tack driver.
A friend has the Volquartson and Savage and loves it.
I am a left hand shooter and would like to see CZ make an appropriate sized action for it and produce it. Cooper, Henry, Ruger, custom makers, help me spend my money. A .20 or .22WSM is fine also.
Most shooters will shoot a heck of a lot more light calibers than big ones. I hope the manufacturers are listening.
