Can anyone provide performance info. on the H & R Ultra Varmint (SS1-822) in 22 WMR? I'm interested in its paper punching capacity at 100 yards (no hunting)? Would it require/respond to additional gunsmithing (e.g., trigger, action bedding, barrel floating)? Is it worth it to buy a Cooper, Brown, Anschutz for best 100 yard accuracy? How does it compare with say a CZ ZKM American? Opinions please.
