When I began shooting rimfire silhouette years ago, my first scope was a Burris 12x with standard crosswire. Later, I bought a Simmons 6-20, but it was junk. Finally got smart and bought a Leupold 6.5-20 EFR with 1/8" dot. That was the ticket. Easy to put that dot on the turkeys and rams, but did not always knock them down. Hard to beat a Leupold.
