What type shells works best in your 930, bird shot, buckshot, slugs or most everything works about the same. I just purchased a 930 with 18.5 inch barrel.
Type of shot doesn't matter much, but you'll have best results with ammo in the 1300+ fps velocity range. The 18.5" guns tend to choke on lower velocity loads and end up with a lot of ejection failures...
