Reloading Die Set Up Straight Walled Cases

This category is for reloading die set up instruction and operation.

Crimp Die Set Up

Consistent crimping is critical from load to load. Take your time and learn it well. With the bullet seated and case in the shell holder, run the ram all the way up. Thread the die body downward until it makes contact with the case. Repetitiously, lower the ram slightly and turn the die downward incrementally in quarter turns and then run the ram back up into the die. Once into the die, wiggle the die back and fourth. Keep repeating this until there is no more play between the die and the cartridge case. Once you are at the point where there is no more play between the cartridge case and the die, the die is beginning into the crimp stage. For turret or progressive presses turn between 1/8" to 1/2" for desired crimp. For single stage, about 1/8" to 1/4". This will be dependent on how much play you removed from the die and cartridge case. Light crimps are minimal adjustments, heavy crimps are max adjustments. Take your time and pay attention to the fine details so when you repeat this process you do it the same every time. If you have questions this is the forum to ask them in. Highboy

Carbide Die Set Up

Raise the ram all the way up to top dead center. Thread the die body all the way down until the die firmly touches the shell holder making sure there is no play in press linkage. Tighten the die lock ring. For turret presses, turn the die approx. 1/8" further for slight cam-over in order to lock the turret all the way out. Be careful not to apply too much cam-over as you can break the brittle carbide ring. This forum is here for additional questions. Have fun. Highboy

Non-Carbide Resize Die Set Up

Raise the ram all the way up to top dead center. Thread the die body downward until the die makes contact with the shell holder. Once contact is made, lower the ram and turn the die downward about 1/8" of a turn. Run the ram back up so the shell holder makes firm contact with the mouth of the die. This is called cam-over. Tighten the die lock ring. Lee presses do not apply cam-over, they go by feel. For turret presses you may need slightly more cam-over to fully eliminate play within the turret.

Expander Die Set Up

Thread the die body all the way down until the die mouth touches the shell holder. Tighten the die body lock ring. Place the case in the shell holder and begin turning the expander stem until the mouth of the case is expanded about 0.012 larger for plated/jackets bullets and about 0.001 larger for cast bullets. For powder-thru dies on progressive machines the die body adjustment controls case mouth expansion. Too little expansion will cause the case to shave the base of the bullet. Too much and the case mouth becomes over worked. For additional information you can ask your questions concerning the expander die in this forum. Highboy

Seat Die Set Up

Place a resized case (not expanded) into the shell holder and raise the ram to top dead center. Thread the die in until it makes contact with the case mouth. It is at this point it will begin crimping and you do not want to seat and crimp in the same step. Therefore, once the die body has made contact with the case mouth un thread the die about 1/4 turn. It is critical that all the cases are of the same length. For my high volume bang-bang steel target ammo where I have mixed cases and they have not exceeded max case length I don't care so much about being several thousandths off. For this scenario I set the seat die to the tallest cases to avoid crimping while seating the bullet. If you have additional questions about bullet seating dies feel free to ask them in this forum. I sure hope this helps. Highboy
