All Lee full length rifle dies feature the Easy X expander. This new expander differs in appearance from the original in that it is tapered.
The expander pulls almost effortlessly though the neck and is designed use the maximum mechanical advantage of the bottom of the press stroke. Like the original, if the expander hits an obstruction, it pushes harmlessly through the decapping clamp which holds it in place. The shank is so strong that you can actually remove stuck cases by loosening the decapping clamp and using a drift punch of the same diameter to knock the case out of the die. The new design also aids in reforming dented or squashed case necks.
It should be noted that the following calibers use a handgun decapper and they do not expand the neck of the case.
30 M1
38-55 Winchester
375 Winchester
45-70 Government
44-40 Winchester
32-20
38-40
444 Marlin
Our Collet dies do not and never have used an expander.
