RE: Do pellets rise or fall between 20 and 40 yards?
If you know about patterns and shot guns, it is very hard to answer this question. Every gun shoots different. My Winchester won't shoot anything you have listed, choke or shell. And I dont care for Truglow sights. I just use the brass bead. I shoot 2 3/4", 1/4oz of copper #4 shot and kill turkeys at 40yds. As far as shot rising or falling that will change from shell to shell. Depends on the speed of the shot. But the pattern will open between 20 and 40 yds, no matter what choke you shoot. You will have to shoot the gun and figure it out.
