Having a rifle built for my Dad by RW Snyder. Specs: LA/RH Rem 700 trued, squared. Brux 26"#7 eq contour. Caliber 6.5X55 Swede. Stock- HS Fully adjustable cheek and lop (forgot model #). This will be a seriously sweet rifle and I'm trying to decide which scope to get him. The 2 that I'm looking at are the Vortex Viper 6.5-20X50 and the Menace 5.5-25X56. That is the price range I'm limited too. Max range used will be 800-1K with most done at 600-800. Any persuasive arguments are appreciated!
