RE: Two Questions Caliber and Scope
Have you looked at the Burris signature series. I have at least 8 Leupolds and 3 Burris scopes. The Burris is a real rock solid scope. It has a posi lock feature that maintains zero year after year. I have not touched my elk rifles scope in three years of elk hunting with plane rides and at least 15 times at the range shooting a ton of 300 WSM handloads. I really like it.
