I shot a seven (7) group, @ 100yds. Shot with Barns bullets military cases CCI #35 primers and H 50-BMG the scope is a Night Force 5.5×22-56. I was accused of intentionally drifting subsequent shots after the center disappeared, so I said I’ll make a Mickey Mouse with the last two shots. As it turns out the gun is better at grouping than I am at art. (It looks more like a Grateful Dead Bear). I have 40 xs, Coopers, SASSs, custom 30 cals, XP-100s in 5 different flavors, and my McMillan TAC-50 is the most accurate shot to shot event to event gun I own, hands down. I wouldn’t be able to do this with out McMillan training your school is awesome!!
