rifled shotgun choke tubes?

[skeet]

Way back yonder when the sabots first came out I bought a bunch of the Smith & Wesson(made by BRI) sabots for police work. Very hard things and had to be shot out of an open choke. Used 'em in a Rem 1100 skeet gun with a weaver mounted scope. They were the best things since canned(or bottled) beer. Still have some in fact...collectible for certain. They would shoot 4 inch groups at a 100 yds...if I did my part. Got an 11-87 later with a rifled choke tube and shot some of those S&W sabots through that with the same scope set up. Cut my best groups to 2 1/2 inches. I was truly amazed. The thing that was so much better with the sabots and the rifled choke was the range increase with good accuracy. They were good for 150-175 yds under good conditions. My previous shooting at a stretch was 125..and that was only once or twice under perfect conditions. on a side note while shooting more than 400 deer(shot on crop damage permits etc) I lost only 1 deer(and it only traveled 35 yds) that hid itself in a pile of leaves in a patch of green briers. I only took shots that I knew I could make. That rifled choke was a big help. I had a fully rifled 11-87 that has taken(by 4 hunters) 91 deer...with 99 shots...and 7 shots were used to sight it in. Hopefully the fellow that has that gun now will extend the record.
