I'm a new reloader using a Dillon 550B press. So far with .45 ACP it had been pretty easy. But I am setting up to make some .357 Magnum and having a problem.
If I bell the mouth of the cases too much, the bullet is pushed all the way into the case. If I bell it less, sometimes the lead bullets I'm using shed a small bit of lead where the edge of the case shaves it off. The tighter mode seems to make better ammo (looking at it, haven't shot any yet), and the crimp is real tight.
Is this shaving of lead unusual?
