i loaded up some 9mm rounds today using my lee die set (three die). grabbed fifty previously sized and belled cases, primed them, filled them with powder, then started to seat the .0358" diameter moly coated lead bullets (bear creek bullets).
the first bullet seated rough, so i checked it out. the moly was scraped off the side of the bullet and the calipers showed only a .356" diameter for the bullet. not good so i took the seating stem out of the die and tried to push a bullet through the die. no go! the i.d. of the die body is too small for this .358" diameter bullet.
finished the session with a rcbs seating die. bullets stay @ .358 " and shoot great.
i've had this problem before with a 44mag seating die and .432" diameter bullets. forgot that lee dies have this "precision" seating feature and won't seat "oversized" bullets properly.
fyi,
