I'll start with the scope and bench rest and see what the accuracy and rule me out as the shooter. Then I will try the same bullets with some different powder variations. Then play with bullet options.
I bought it from a respectable small gun shop used. The guy they bought it from was one of their regular customers, and had used it for a few seasons, and switched when the Remington came out with the 26 inch barrel version of the .50 cal.
