REDDING - 40 S&W Carbide GRX Push Thru Size Die

You can use this die on .40S&W or 10mm brass either before or after a full length resize, depending on your press setup, and your preference of lever arm resistance. Works exactly as intended. Hopefully Redding releases 9mm and .45 auto dies!

I use the die to remove the bulge on my 10mm brass which is inherent when fired from a Glock. The die is easy to adjust and works great. Even though it's a Titanium Carbide die, I do lube the cases slightly just for grins which make the use even easier. It will work just fine without lube, but it's my own personnel preference. I've used the Lee Bulge Buster and this is far superior to it. I highly recommend this die.

I used the GRX die to fix my bulged 40 Cal and 10mm brass, the result was great on both calibers. They are all resized back to factory specifications of 0.423" diameter. The bulge has been removed and once I started loading, the crimp was very positive and firm in place. I hope in the near future Redding offers this great GRX product for 9mm and 45 ACP.

An excellent product offered by Redding. I have run my bulged 40 Cal Brass through this Die and the result is fantastic. All the Brass are reshaped back to the original specs, so now I could load and shoot them in my Match chambers.
