Ok in a pump action shotgun ghost loading can add 1 more round but in a semi auto it you can add 1 more round as well. I've found out if I ghost load my Fabarm SAT 4 (semi auto) It's designed for 3 inch and it can only hold 4 in the tube 1 in the chamber but if I goto target loads I 2 3/4 I can fit 5 in the tube and 1 in the chamber but if I load 1 more as a ghost load I can fit 1 more I know it's meant for 3 inch so it only matters for that one but the question is if I ghost load 5 3 inch and 1 in the chamber it's still legal. Some 2 3/4 inch shotgun shells I can fit 6 in the tube and still ghost load 1 more giving me 7 rounds out of a semi auto shotgun as long as I shoot the smaller ammo ie not 3 inch. So is this legal or not since it's designed and manufactured for 3 inch shells and can only hold 4 in the tube unless you ghost load and then it's 5 and 1 in the chamber.
