It was with reduced recoil Fiocchi 00 buck 1150 fps. Of the 10 shells in the box 3 did not eject. When it malfunctioned the hull was half way out of the chamber and a new shell was out of the magazine jamed under the spent shell. To clear I just had to pull back on the bolt handle to complete the cycle. I have about 200 trouble free rounds through my 930, all were over 1200 fps. After another 100 rounds I may try them again. Not to concerned because in my other shotguns for home defense I always use 00 buck that have no less that 1345 fps
