Straight-walled brass tubes, ready for you to neck down.

In years past some casing manufacturers sold straight tubes like these, that they called “BASIC BRASS.” Peterson refers to its BASIC BRASS casings as Wildcat Tubes. 

Each Peterson Wildcat Tube starts with the same brass raw material as other Peterson rifle casings. We process them using the same draw tooling. The headstamp is blank, except for Peterson’s “P” inside a Keystone (a nod to the fact that we are located in Pittsburgh, PA; and PA is the Keystone State.)

We then insert the flash hole into the primer pocket. And finally we anneal what will become your mouth, neck and shoulder portion, to make necking-down easier for you.
