I shot some Remington copper solid 3" sabots out of my 870 26" barrel with an extended rifled choke. I fired two at a target at about 50 yards. After examining the target there is a perfect outline of the side of the slug. Somehow the slug turned 90 degrees and went through the target sideways. The other looks like it went through at about a 45 angle. Now I didnt expect pinpoint accuracy with just a rifled choke, but I at least expected it to go through the target front first! So I'm thinking maybe i should try a smaller slug so the rifling in the choke can have more of an effect on it. What do you guys think?
