Best thing for rifle brass is roll sizing. There are a few different ones out there. It is mostly commercial reloaders using these machines but there are price ranges for most shooters available.

Even a standard Lee sizing die will do that, whereas Dillon sizing dies don't. That's because they've got a design "feature" that other manufacturers don't use. They radiused the mouth of the sizing die enough that it doesn't size all the way down to the bottom of the case to give you better indexing. This means that if you don't open the die up, you may have to move the case/shellplate with your finger to get it to line up right from time to time.

In addition to not eliminating the Glock bulge, they can also give you a finished round that will occasionally fail to chamber in a match chamber. Three different members of my weekly shooting group have had this problem with Dillon Sizing dies. They all went to a Lee Sizing die to fix the problem.

Sizing/Depriming Die
The primary feature of Dillon's size die design the long, tapered carbide ring with a radiused opening, remains unchanged.

The radiused opening, and its importance to progressive reloading, is one of the reasons why our seat and crimp dies are better. We found a way of manufacturing these dies that has enabled us to make the lead-in radius even bigger! The bigger radius makes progressive loading with our equipment even smoother but that's still only a part of the story.
