All Dillon Pistol Die sets include our sizer/decapping die, seating die and a separate crimp die (taper crimp for auto cartridges, accu-crimp for revolver cartridges).
Our sizing/depriming dies feature a unique “floating decapping assembly” with a snap spring that throws the spent primer off the pin and eliminates the problem of primer “draw back” that often occurs when decapping military brass. The primary feature of Dillon’s size die design the long, tapered carbide ring with a radiused opening, remains unchanged.
The radiused opening, and its importance to progressive reloading, is one of the reasons why our seat and crimp dies are better. We found a way of manufacturing these dies that has enabled us to make the lead-in radius even bigger! The bigger radius makes progressive loading with our equipment even smoother but that’s still only a part of the story.
Bullet Seating Die
Our new quick-disassembly seat die allows the user to disassemble and clean the seat die without losing adjustment. In this manner, bullet lube and shavings can be quickly removed from the die, thereby guaranteeing a constant seating depth. We’ve incorporated a “flip-flop” seating stem and a clip that enables you to remove the die insert and change the seating stem from round nose to semi-wadcutter without unscrewing a seating stem out of the die body. We’ve always included both types of seating stems, but the new double-ended design makes it a simple matter to remove a pin, reverse the seating stem, make any minor seating depth adjustments that may be necessary and go on loading in a fraction of the time it used to take.
We’ve made it easy for you to remove the die insert for cleaning without having to change the critical crimp adjustment. Once your crimp die is set for the proper amount of crimp, you’ll never have to change it. This is especially good news for all of you who load lead bullets! Before, you had to unscrew the die from the toolhead and disassemble the die in order to remove any bullet lube or lead residue. Then, you had to start from square one to re-adjust the crimp. Those days are over. All you have to do now is pop a clip and the die insert drops into your hand for cleaning.
Dillon Three-Die Rifle Die Sets include a sizing/depriming die, a bullet seating die and a taper crimp die.
The sizing/depriming die is full-length and sized to minimum tolerances to size cases down to function in both semi and fully automatic firearms. We strongly suggest that a headspace case gauge be used to correctly adjust the size die.
For high volume users, such as commercial reloaders, law enforcement agencies, and high power or service rifle competitors, we also offer .223 and .308 die sets with a full-length carbide sizing die. Lubrication is still required, but the increased scratch resistance and die longevity of carbide are of great benefit to these groups of users.
The depriming assembly includes a carbide expander ball for “squeak-free”, effortless, neck expansion. This expander ball is located in the middle of the depriming stem to take advantage of superior initial leverage for easier extraction.
In the event of a stuck case, the design of the depriming assembly allows it to function as a stuck case remover.
Bullet Seating Die
Our bullet seating die is internally designed to keep the bullet straight throughout the seating process. Once properly adjusted, the only measurable runout will be that which is inherent in the bullet.
Taper Crimp Die
The taper crimp die is also specially configured to center both the case neck and the case body, thereby aligning the entire cartridge for a more uniform crimp. Dillon Rifle Dies are designed to meet the more rigid requirements for both accuracy and precision demanded by today’s marksman.
A taper crimp die is preferred for loading ammunition intended to be used in semiautomatic firearms with detachable box magazines, and in lever-action firearms with tubular magazines.
We strongly recommend using a headspace case gauge when loading bottleneck rifle cartridges.
Rifle headspace case gauges assist in proper size die adjustment and in checking cases for whether they need to be trimmed. Essential for long case life, especially with semi-automatic firearms! Dillon Precision headspace case gauges are made of stainless steel for long life.
