Rifle headspace case gages assist in proper size die adjustment and in checking cases for whether they need to be trimmed. Essential for long case life, especially with semi-automatic firearms! Made of stainless steel for long life.
***Please note: Dillon case gages are machined from stainless steel. They will have dings and scratches. This is the same regardless if you get them directly from Dillon or from us. Scratches and dings do not affect the usage of these in any way. If you are expecting a perfect piece of polished steel, these are not for you.***
