FEW YEARS AGO WHEN I BROUGHT MY MOSSBERG 835, I SIGHTED IN WITH 2.75" LIGHTFEILD SLUGS, AND I WAS SHOOTING GREAT!!!!! WHEN I WAS DONE AND CLEANING UP THE EMPTY SHELLS & BOXES I READ THE SIDE OF THE BOX AND IT SAID " DON' T USE IN RECIVERS THAT ARE 3.50" WHICH IS THE 835. WELL I CALLED LIGHTFEILD THEY SAID THERE IS SLIM CHANCE THE SLUG CAN GET HELD UP. SO I TRIED THE LIGHTFEILD 3.50" SLUG THATS LOADED TO 3" SPEC. WELL I' M SHOOTING GREAT AGAIN, AT 2" HIGH AT 50YDS.
