Lee Loader Seating Depth

First make sure that when you resize the case, you drive it in so the base of the case is flush with the bottom of the die (one can even go a little below flush). This will provide the tightest bullet fit. One can use a factory loaded cartridge to set bullet depth. Place the loaded cartridge in the decapping chamber as in step #4. Assemble the die as shown in step #7, with the stop collar turned all the way up. Place the bullet seater tool in the top of the die as shown in step #7, it should drop all the way down to the stop collar. Now turn the stop collar down until the bullet seater just begins to rise up off of the stop collar. Where the bullet seater separates from the stop collar is the factory bullet seating depth.
