I have a Rem 870 20 ga Express Compact Camo that I've decided to play with this year. I've purchased two Carlson chokes, one a Longbeard XR and the other is their TSS choke as well as trying the factory .572 turkey choke. In trying all different choke tubes with a variety of different lead and TSS ammo, the gun is shooting a minimum of 16" high at 40 yards. This is with the bead looking straight down the vent rib. This is with a 6:00 hold with no rib showing. I'd like to stick with the bead and am reluctant to go red dot. Short of aiming at the turkey's feet, what options do I have to get the gun setup to hit to point of aim?
