Automotive Anti-sieze and lot's of it is what I use. Also I don't crank the BP down as hard as possible. I turn it down till tight then back it off just a hair. When I'm done shooting I loosenit off before I leave the range.

My first ML'ing deer fell to 2 T7 50 gr pellets, 300gr SST out of an Omega. The deer staggered 20 yds then dropped.
