You fart smellers correct me IIW and I know you will but I have three model 12s and near as I can tell, there is nary a one in which the base of the last shell is held flush with the end of the mag tube as in say an Ithaca 37. In every one of mine the base of shell is held in place by the forward part of the lifter and protrudes from the mag tube. I've shot countless rounds of skeet with one in particular (a composite gun with Barnes barrel and them chock tubs that the fellers on the old Shotgun Sports board were always talking about). I've always loaded this way; never had a slamfire UNLESS I intended to do so (trigger held); never had feeding problems. What pray tell am I doing wrong?

I have a second m12 skeet gun so marked and have had trouble with the "wishbone" on the side of the bolt clearing em out of the chamber. I replaced the ejector and it still stovepipes the empties occasionally. These are the ones I always toss in the bushes (emphatically)particularly if it acts up on the first shot of double stations.

I have a third "factory" skeet with a plain barrel and a Cutts collet choker on the bizend; a nice gun and little use but a bit muzzle heavy. Enuf rambling a la my hero Francis. To the OP, you better read the wonderful MMc short story "Knowing How, Knowing When" if you haven't already. Old man McI figures prominently in that one, but the gun du jour is I believe a Remmy 31. Foxy will know.
