Had my 378-338 out last week after sitting in the safe for six or seven years, 2 old guys and 2 young guys with onely one of us ever shot it before( me of course ) without touching anything but the trigger, 2 1/2 high at 120 yds, dead on at 406 ( rangefinder) old guys 6" groups, young guys 3 1/2, bench rest, sand bags. 400 yds no big deal don't you just hate those young eyes and reflexes. By the way, weatherby alaskan, 340 chambered out to 378-338, custom muzzle brake,4 1/2x14 leupold, dead calm ( as a by the by, I live about 10 miles from the Leopold factory ) all my scopes are leupold
