Why wont my Dillon resize cases to their apropriate length.
Okay, so I just setup my new dillon 550b and installed the decap/resizing die. Screwed it all the way to the shellplate, backed it up just enough to free the shellplate, tightened the lock nut, and threw in a case to try it. It decaping works and the sizing lengthens it by .005" but still doesnt bring it to the .898 its supposed to be. It just gets as far as .890 (formerly .885) I cant lower the die anymore! (yes it is the right conversion kit/dies for the cases Im using) can anyone tell me whats wrong?

What makes you think a sizer die should LENGTHEN a shell? They sometimes do get longer during the sizing process, but not always. If you want a certain length that's longer than the shell already is, you have to fire them and resize repeatedly to make them grow.

You don't state what the Cartridge is but I would be very happy if I was you. If its for a Pistol cartridge like a 45ACP or 44 Mag it is not going to get longer when it is re-sized. Don't sweat it. If the cartridge will chamber go with it and be glad you don't have to trim brass, which is one job I really dislike.

Because the sizing die only decaps and sizes the body, neck and shoulder. It's not a trim die.

Your loading manual should give you the Maximum Case Length and the Case Trim Length. So long as your brass measures within these two extremes, your length is fine.
Judging from your measurements, I leap to the conclusion you are talking about a pistol cartridge of some kind. Hopefully one that headspaces on the case mouth. Perhaps .45 ACP? In my Hornady manual under .45 ACP, the Max Case Length is .898. The Case Trim Length is .888. Anything in between should run fine in a factory chamber. If you are indeed dealing with a cartridge that headspaces on the case mouth, you do not want to go longer then Max Case Length. A cartridge that headspaces on the rim on the other hand, is much more forgiving of case length. I've never trimmed my revolver brass... Ever... |

Pistol brass doesn't need to be trimmed.

Pistol loading isn't rifle loading. Pistol cases get SHORTER as they're reloaded. Why doesn't the Dillon makes cases the proper length? Because it's not a case trimmer. If the cases vary in length, as range brass does, then you'll still see that variation after sizing. |

I reload .38/357,.45ACP, 9MM. .44Mag and .45 colt and have NEVER trimmed a case yet.
