9mm luger
Dillon 550B
Dillon dies, carbide inserts
I've set up the 550B and all dies as recommended. Specifically with the sizing die, I raised the shell plate completely and threaded the die, lowered it completely to make contact with the plate, and then tightened the lock nut.
Well, I ran a few once-fired cases through and the die only sized the shell about 2/3 of the way down the body of it. So, the upper 2/3 of the case is sized and slightly narrower than the lower 1/3. As I'm a novice, I decided to continue the process: I primed it, placed the charge, seated the bullet and crimped it. Now, the shell's diameter is larger where the bullet was seated and near the base of the shell, but in the middle 1/3 it's extra narrow. What the heck? Just to make sure it wasn't the brass, I tried it with a new case and got the same results.
I was sure to pull the operating handle all the way down...any chance the sizing die's insert is the wrong diameter? I was a little frustrated and so stopped and packed up right there for the day and didn't take the time to measure the resized case diameter (the thinner portion), but it definitely looks narrower than a new case to the naked eye.
Help?
