I use a Remington SP-10 tuned and polished by Joe Morales at Rhino Gun Cases. I use a Rhino Choke and Nitro Ammo (Straigh #4 Hevi shot, 2.5 oz). I can put one down at 70 yds, but I hate to shoot past 40. That shot was a hurried one and I couldn't get my range finder out before the bird would have topped the ridge and disappeared. Topped by an EOTech 553.

A 35 yard target I shot with my 10 as I was sighting in my daughter's Remington Youth Model 11-87 topped with a Bushnell Holosight.
