Neck & Throat

Often used for wildcatting, when a smaller caliber cartridge is necked up to a larger diameter. The smaller chamber reamer is used with an appropriate for barrel pilot to cut the body and set headspace, then the neck and throat reamer is used to complete the chamber.

These reamers incorporate both the neck and throat features for any given caliber. Reamers come with either solid and removable pilots. Dimensions are designed to provide a standard chamber for the specified caliber, that means the neck will normally be about .004” over the diameter of the loaded round. Throats will be normal length for the given caliber.

Any reamer with special or out of the ordinary dimensions will have the information included in its description.
