Check the alignment. Sounds like one of your cartridge stops is crooked. Pics?Well finally got around to putting some live ammo through the KSG about 50 slugs and some double ought all 3" shells; anyway the right feed tube works as advertised but the left is a far different story. The left tube does not release only one shell it lets two slide out and will not feed the first released due to the other shell being in the way. Any thoughts?
