I have a Remington 870 with a rifled cantilever style barrell and am in the process of seeing which one of the lighter and faster sabots will shoot the best out of it. Which one are you guys having the most luck as far as accuracy and knockdown power go? I plan on trying the Rem Corelockt.Win Partition Gold,Win Platinum Tip, and the 325 Grain Federal Barnes Exp. to start with. Any others you guys would suggest?
