Tighter Tolerances
These die plates are CNC machined to the highest standards. All critical machining is done on one operation, yielding tolerances of 0.0002" on all critical dimensions. This means that all die mounting holes are positioned precisely relative to each other and are exactly perpendicular. The 7/8"-14 die mounting threads are machined to Class 2B tolerance to better mate with the threads on your dies. This results in the dies being more accurately centered in each hole and reduces offset when tightening the die locknut.
6061-T6 Aluminum Alloy
The toolheads are machined from 6061-T6 aluminum alloy. The T6 tempering process yields an ultimate tensile strength of at least 42,000 psi. These toolheads are full thickness with no voids or cavities on the bottom.† The end result is a toolhead that is about 80% heavier than a cast toolhead … and much stronger with less flex.
Q: How can I use the Light-Load™ with this die plate?
A: If you do not have an empty die station, simply drill a 9/16″ hole in the center of the die plate. The die plate is solid metal and plenty strong enough that this will not weaken the die plate.

TIP: Swap Out Your RCBS Die Lock Rings The RCBS 1-3/16″ Die Lock Rings don't leave much space for a wrench … and the RCBS Die Lock-Ring Wrench leaves much to be desired. But there is a solution! Just swap out the RCBS Die Lock Rings for Dillon Precision 1″ Die Lock Rings. You will gain enough clearance to use our Die Wrench for Dillon Presses. The photo at left shows a pair of Dillon Powder Dies with 1″ die lock rings. With the die wrench engaged on a die lock ring, there is still plenty of clearance! |
| † The only void on the bottom is a central counterbore that provides clearance for the Pro Chucker 7 shellplate lock nut. |  |

The RCBS Brand cast die plates are rough and incredibly disappointing. The Uniquetek version is smooth. The die slide in perfectly. No rough threads to cause issues like the RCBS version. The fact that you have to buy that obnoxious powder measure (which is as accurate as using a scoop) with the OEM makes this one a much better deal. I don't mind swapping out powder die. In fact, now I have an excuse to use the Hornady measure which is more accurate.
Note to users: DO NOT over tighten the set screws on the press (with this or OEM die plate). The point of the set screw is to keep plate from rotating out. No reason to tight much at all. I feed screw down then I back it off a turn or two. The die plates are meant to float. The press should be the stop in the upwards direction (not the set screw). If you don't follow this recommendation, you will strip the screw threads in the press. Ask me how I know. ;)
