Ranman, my top barrel I went with a Patternmaster code black Turkey .515 with Salt Creek 1 1/4 ounce #10's. I get 368 bb's in a 10 inch circle at 40 yards. It's good from 26 yards to 40+. The bottom barrel is my open barrel and I have a Sumtoy .540 choke in it and I'm shooting a duplex load 1 1/2 ounce of 8 1/2x 9 1/2 which is good from 10 yards to 30 yards. I'm using the factory bead and with the top tight barrel I aim at waddles and with the bottom barrel open choke I aim between the waddles and the head. It's a very handy and versatile Turkey gun.
