Dies are where your brass actually takes shape. They size the case, seat the bullet, and crimp it in place. This collection covers die sets for hundreds of rifle and pistol cartridges from Hornady, RCBS, Lee Precision, Redding, and Lyman, along with the bushings, lock rings, and decapping parts that keep them working.
How many dies do you need?
Most bottleneck rifle cartridges load with a 2-die set: a sizing die and a seating die. Straight-wall pistol cartridges usually come in 3-die sets that add a case-mouth expander, and carbide pistol sets let you size without lubing each case. A 4-die set adds a separate crimp die, so seating and crimping happen in two steps instead of one.
Full length, neck, or bushing sizing
A full length sizer returns the whole case to factory dimensions. It's the safest choice for semi-autos and for brass fired in more than one rifle. Neck sizers, including collet-style designs, work only the neck on brass fired in your own bolt gun, which can extend case life. Bushing dies take interchangeable neck bushings from Redding or RCBS so you can set neck tension to the thousandth, and match-grade sets from Hornady and RCBS add micrometer seating stems.
Picking the right crimp
Revolver rounds with cannelured bullets get a roll crimp. Semi-auto pistol rounds that headspace on the case mouth, like 9mm and .45 ACP, need a taper crimp instead. Separate crimp dies from Lee Precision and others are popular add-ons for both rifle and pistol loads, especially when you want seating and crimping as separate steps.
Small parts that save a session
Keep spare decapping pins and lock rings on hand, since a bent pin can stop a session cold. A micrometer seating stem helps when you're fine-tuning seating depth, and a good sizing wax keeps tough rifle brass from sticking. Some die sets include a shellholder and many don't, so check each listing and shop shellholders separately if you need one.
Putting your dies to work
Most dies thread into a standard 7/8-14 press, so they'll fit the single stage, turret, and progressive models in our reloading presses collection. The exception is .50 BMG and similar large calibers, which use larger dies and need a press built for them. Lube and prep your cases first with supplies from case prep tools and case lube, and keep a current reloading manual on the bench for die setup and data.
