Dillon handgun case gages allow you to check your handgun ammunition to ensure it will fit a minimum sized chamber. Made of stainless steel for long life. <br /><br />***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.***
