CZ 452 or 455 are the most bang for the buck you'll get in a bolt action 22LR. Scary accurate rifles, especially for the money.

Not many folks are fans of Savage, but I have a couple Mark II's and 93's which shoot lights out. My latest, is a Mark II FSS I picked up for my son last winter, with plans to cut it down to 16" and cut the LOP to 8.5" on a Boyd's pro-varmint stock to fit his now 4yr old frame. He has been doing well with his Marlin 60, so I left the stock alone, through a demo Bushnell Trophy 3-9x mil-dot on top, and I have been shooting it myself all summer at 300-350yrds as a practice rifle.
