A foolproof way to check and shorten cases. Run a case into a Trim Die and see if it sticks out the top. If it does, just file it until it's flush.
Doubling as a case length gauge, this die will quickly allow the reloader to see if the case is too long. If the case is too long, the case will stick out above the top of the die. To get the case to the correct size, file the case down until it's flush with the top of the die.
The Trim Die has been case hardened, hand polish and heat treated to withstand a file bearing against the top surface without causing damage to the die. Shell holder sold separately.
