Redding G-Rx LogoThe G-Rx Push Thru Base Sizing Die, from Redding Reloading Equipment, is designed to restore fired cases from .40 S&W autoloading pistols that exhibit a bulge near the base. The G-Rx Die fully resizes the bulged area of the fired case back to within the accepted SAAMI specifications for case diameter. The case may then be resized in a standard sizing die for the remaining reloading process. Also sizes 10mm Auto cases.

It's just what the doctor ordered to cure your bulged .40 S&W cases.

The Redding G-Rx Push Thru Base Sizing Die set is comprised of a pusher rod which fits into the ram like a shell holder plus the unique push through sizing die with lock ring. To use, the case is set on top of the pusher. Then the ram is raised to push the case entirely through the die. The die has a rebated section at its top to hold the finished case so that it may be easily removed. With the Redding G-Rx Die you can remove the bulge from literally hundreds of cases per hour preparing them for the reloading process.

The G-Rx die also works on 357 Sig Brass!
The 357 Sig has the same base dimensions and therefore the Redding G-Rx die for 40 S&W can act as a perfect base sizing die for this caliber as well.

WARNING: Do not use to size live ammunition!
