[QUOTE="brentc, post: 1061058, member: 16938"] Generally, the guys that need them most are the guys that partial full length size their case, meaning, once the case is fireformed, they size the shoulder of the brass down .001-.002" and headspace off the shoulder instead of the belt. What this does is gives your brass a better fit in your chamber, however, it also results in a section of brass right above the belt that doesn't get sized. The unsized section expands a little every time you fire your brass causing the case to eventually become hard to chamber, or stick in the chamber after it is fired. The problem is most common in loosely spec'd chambers that allow the expansion to take place. Larry Willis' die sizes the expanded portion so you can get more life from your brass. As stated earlier, it works as designed if you need it. [/QUOTE]
