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.
|† The only void on the bottom is a central counterbore that provides clearance for the Pro Chucker 7 shellplate lock nut.|

Pleased with minePurchased two. Much more efficient than buying the overpriced OEM plate. Nice, clean and strong, works as advertised.
Work of art!I was incredibly pleased to see you offering this die plate. I ordered a couple to try. They are great. I plan to order more soon. It is well built and pleasant to look at. I plan to drill a hole in the center for a light because this press is so dark. I wouldn't consider doing that to the OEM cast version which would probably bend with such a modification.
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. ;)
