rifled choke tubes havea hard time kicking off the sleeve of the sabot making it less accurate than even a rifled slug. my opinion is unless you have rifled barrel, dont waste the 10 bucks for 5 shells. or the 50 bucks for a rifled choke tube. i bought two lastyear and me nor my wife ever used them once during season becausethe groups sucked so bad. either buy a rifled barral for just use a rifled slug withic choke tube in.
