    Enter exact desired custom neck dimensions in box below.


    For reference, these are our standard neck dimensions found here.

    Please Note

    To determine the neck diameter in a Custom Non Bushing Sizer we recommend the following formula

    Average bullet diameter + Brass neck thickness (number x 2) - .003 thousandths = ?

    Applied to a 6mm Creedmoor 

    .243 +.014 x 2 (.028) = .271 - .003 = .268   .268 would be the sizing hole diameter

    Note: Ensure you measure the brass neck thickness not the neck diameter for this formula.
