I bought a Remington 40 XC in 7.62 Nato with a Kevlar stock several years ago. I bought this gun to shoot the highpower National Match course and got some good groups from a bench with a scope on it. My best five-shot group was .348" at 100 yards. I just couldn't shoot it well with open sights. What other courses of fire could I shoot with this gun in this caliber if I use a scope?
