MATERIALS LIST

You should bring at least one pre-turned barrel blank (select a contour that you want) and a bolt-action receiver. Just in case you finish before the five-day class is over you may wish to bring another barrel and action to get started on. Since this is a basic rifle barreling class, please bring only bolt-action receivers for barreling.

We will have you preparing the actions by facing off the front of the action to square it up as well as lapping the locking lugs and possibly welding and re-drilling the firing pin hole. We will then have you thread, chamber, headspace and crown your barrel. There should be sufficient time to polish and blue your barreled action as well.

The school has a small selection of the most common caliber reamers. On some caliber you will need to bring your own reamers. Often our students simply wish to use their own reamer and headspace gauges in order to have identical chambers in several firearms. Please call if you have any questions.

We look forward to seeing you.
