Whidden Gunworks has now developed a system to match our seater stem shape exactly to the bullets handloaders are using. Our Seating Dies include a seating stem that we’ve designed to work well with a wide range of bullets. However there is now a chance to optimize bullet seating and eliminate marking the bullets while seating through the use of our bullet specific seater stems.
Our list of Standard Seating Stems for each caliber. Unless specified otherwise, this is the list of stems that ship standard with our Micrometer Seating Dies.
