What's Included

Popular Questions

1. How much bell should I put in the case?

After flaring, measure the inside of the case just below the flare. Ideally you want to see .003 to .004 below bullet diameter. This ensures correct bullet tension and proper crimping tensions. 

2. How do I choose the right expander die for my needs with so many options on the market?

There are several types of flare expander dies on the market today, each with different pros/cons as well as different capabilities. It is recommended that you use a set of dies that are matched. For instance, Mighty Armory reloading dies work together as a measured system - size, flare, (optional) seat and crimp. Using a measured system makes loading easy and efficient – Think SAAMI spec for the best results!

Instructions

Step 1: Turn the flare die with bushing into the tool head exposing about 1/2 inch below.

Step 2: Set a case in the plate or holder and flare the case. Measure the inside diameter of the case mouth using the back of your caliper. Flare should be .005 under bullet diameter.

Step 3: Find your desired setting by turning the flare expander shaft up or down. Bullet should set into the flare and stay in place when turned up-side-down.

Step 4: Lock the locknut into place.

Flare measurements depend on bullet diameter:
9mm & 38 Super: Flare to .381 to .383
.38 Special & .357 Magnum: Flare to + .002 to .003
.40 S&W & 10mm: Flare to .423 to .425
.45 ACP: Flare to .474 to.475
