Crank Arm has not traveled its full distance or tries to over travel, cycle the Operating Handle up and down slightly
(from the bottom of the stroke) while threading the Powder Die up/down with your fingers while holding the

Belling (flaring) the case mouth--With the empty case from the previous step in Station 2, cycle the Operating
Handle down and back up. Remove and inspect the case for proper belling—see below. Adjust-thread the Powder
Die up/down a small amount (~
⅛
turn) at a time with your fingers while keeping the Powder Measure from
rotating. Place the case back in Station 2 and repeat the test until the proper amount of belling is attained. The
desired amount of bell/flare is just enough to allow the bullet to sit on the case mouth without falling off/over and
to keep the case from shaving bullet material, especially with lead bullets. On handgun cartridges, a sized belled
(flared) case mouth diameter should measure approximately .010" larger than a sized case. Note-over flaring can
be corrected by gently resizing the case in the Size Die in Station #1.)
