Here are terms from the compendium of reloading terms. You should know them in order to communicate effectively.


Cartridge - Complete unit of ammunition, comprising cartridge case, bullet, powder and primer.
Case - Hollow brass container housing the propellant of a cartridge, the neck of which grips the bullet, and the head of which accepts the primer.
Case Trimming - Shortening cartridge cases to specified length after resizing/firing has stretched them. This is done to ensure uniform grip on the bullet, and thus better accuracy
Overall Length ( OAL or COL) - The total length of a cartridge, measured from bullet tip to base of case.
Trim-to Length (or minimum case length) - In handloading, the length a cartridge case should be trimmed back to after it has stretched past its "maximum case length".

Your bolt will not close on cases that are longer than maximum case length. Likewise if the cartridge length is too great, it will not chamber.

Other things to look at are the shoulder of the case. Often beginning reloaders will overcrimp and cause a slight bulge outward at the shoulder. Examine the case at the shoulder to make sure this is not the problem.
