I own a Traditions inline that has given me multiple problems in the past with the breechplug seizing after a day's shoot. I have never experienced that problem again ever since I place plumber's tape (yellow better than white) with a small dab of high-temp automotive anti-seize on the inside and out.
Another trick that REALLY works is to take a small break after your first or second shot, unscrew the breech by just an eighth of a turn and re-tighten. The pesky powder residue that causes the binding is forever broken and can't reform again.
I've since added a CVA Wolf to my collection, an absolute joy to tighten and untighten -by hand no less...- the knurled breech, no matter how many shots were fired.
