[QUOTE="30BR, post: 2101939, member: 64079"] I use a 21st Century arbor press with strain guage to see how much pressure it tales to seat my bullets. If you use a bushing .003" smaller than the diameter of a loaded round, you probably won't notice any reduced seating force. If you are not neckturning with a BR chamber, and seating soft, you are probobobly using about 100lbs of seating force, and I doubt that lubing the case mouth will be the difference between a bullet staying put and setting back. It usually only accounts for1 or 2 lbs of force in my set up and I'm down to about 12 lbs in some applications, and about 40 in others. When I used the std .002 bushing method as I had before getting this press, my seating forces were off the scale (max reading is 100 lbs.). Adding neck lube was not going to impact that number .
