Brand New Redding Carbide Dies Shaving My 40 Cases Badly!

Here's why it happens . . . .
I've seen this symptom a jillion times before, and this is especially common with high pressure from .40 Caliber handloads. The .40 Cal. has a fairly unique handloading problem. It's important to recognize "Glocked" brass. Generation 3 (and earlier) Glocks are especially bad at bulging cases, and that makes them a bit too large to resize.
This problem occurs on the thicker part of brass (at the transition to the web). Redding makes another push-through die that prepares bulged cases for resizing. Unlike an ordinary carbide die, this push-through die allows you to push your case into a shoulder (not away from it). That prevents the carbide ring from popping loose. This push through die also pushes cases completely through the die, so it can resize cases lower than when using a shellholder.
I devised a carbide push through die (about 10 years ago) that is identicle to the Redding die. However, I couldn't produce it at an affordable price. This push-through die is very impressive. Lee makes a cheaper version, but I prefer the Redding carbide die.
