Maybe if he would have asked about form and breathing and such, you could have helped out with that. He asked about equipment and opinions of said equipment.

PS: RCBS claims their X die will not cause the case to lengthen over multiple sizings. Not quite what pupdaddy made it sound like but I'll assume this is what he meant

From there website:

Trim a bottleneck case once—and never trim again with the X Die Full Length Die Set, which includes an X Die Sizer and Standard Seater Die. The sizer features a specially designed mandrel with an expander ball and decapping pin attached. The patented design eliminates the need for repeated trimming after an initial trim of .020 inch off the maximum length to standardize the case. The X Die doesn’t shorten the length of the case: The mandrel reduces the growth caused by the case mouth contacting the mandrel during sizing. Because of an extremely close tolerance between the mandrel and die neck wall, the neck wall of the case does not thicken as the case length is pushed back. Cases repeatedly sized in the X-Die will initially grow a few thousandths of an inch, and then stabilize below the maximum case length with no discernable loss of accuracy or case life. Note: Reloaders who already own a regular set of dies for the chosen caliber need only order the X Die Full Length Sizer.
