That is why I picked 1.6" long for the cases. At that length they would accept the size boolit I wanted to use, .433" Of course this is with 8mm Lebel cases, if you use 348 the length may be different.
The nose on that Lee boolit is really fat, you may have to seat it shorter. The normal boolit has quite a taper to it judging from Chicken Thief's drawing. Oh, Accurate Molds does list that exact same boolit in their catalog.
