Our X-10 press case locator buttons are slightly larger diameter to reach smaller 9mm, 223 and 380 and also taller to ride higher on the case to improve function of the press shell plate helping prevent case tipping along with improving case centering into your dies. 
 
The buttons are plastic with quality brass threaded inserts and they are a direct replacement for the stock locator buttons that come with the press. 
 
The locator buttons work with the listed caliber cases only.
 
Included: (8) X-10 Press Locator Buttons (One Set)
 
NOTE 1: The buttons have a long service life, but are plastic and subject to wear over time making them a consumable item. 
 
NOTE 2: Some of the X-10 223 shell plates are a slightly larger diameter and may rub the locator buttons slightly between stations, this is normal. 
 
NOTE 3: The buttons do not require much torque to stay tight, please do not over tighten the locator buttons. Over tightening the locator buttons or using a flat blade screw driver that is too small may damage the groove.
