But there is a way!
Yes, A-MERC brass is terrible. It's much harder than other brands, and thicker as well.
You can still make usable cartridges from A-MERC brass if you do the following:
Use a generous belling. The narrow mouth of the A-MERC brass will make this necessary for you to have any hope of seating a bullet.
Then, after you crimp the round, run it through a Lee Carbide Factory Crimp Die. Something happens during the seating process that creates a bulge in the middle of the case. The Lee Carbide Factory Crimp Die will eliminate the bulge.
I still prefer to toss it out, though. Many a time, I have seen a piece of A-MERC brass that has an off-center flash hole. I haven't bent a decapping pin yet, and don't intend to on a piece of A-MERC brass.
