I'll just tell you what I shoot. The gun isa Remington 11-87 Super Magnum. The last 2 years I was shooting with a Truglo StrutStopper choke tube and Remington Hevishot 3.5in 6's. I killed bird at 55 yards with that setup 2 years ago. Last year 35 yards was my farthest shot. This year I plan on shooting the new Hevi-13 loads through a HS Strut Undertaker choke tube. Just ordered the choke. Man I'm getting excited!
