If your belief is a rimfire is a rimfire then you probably won't think the 22 Mag is much different than the 17HMR. On the other hand , if like me you view the 17 hmr as different than the 22lr you will enjoy the 22 mag. I think my 22 mag has much more thump than my 17hmr. I'd also personally view the high velocity 22lr as the midpoint beween the other two ,if there is a midpoint. They are really three quite different critters in my humble opinion.
