I have several of the old steel tube Weavers that I use. The pigs that I kill with my Mule gun (1965 M700 30-06) don't know it is a 35 yr. old Weaver Marksman that targeted them.

I also have a Weaver K2.5 post&crosshair that I use on a 8.5 lb. .416. So far it has survived several hundred rounds of 350 gr. at 2550.

Tough old scopes.
