Thanks to all for the info shared.. I have a pretty good idea as to the necessary steps for success... but, one last question.. how far should the barrel screw on by hand, prior to wrenching it up to alignment.. I've read that the extractor width and no more is acceptible, others have told me 1/8" is enough... seems like it gets pretty tight, pretty fast!

.... Best to all, til...lat'r....GT
