Voyeur’s Guide to Barrel Chambering On Rifleman’s Journal

On German Salazar’s Rifleman’s Journal website, you’ll find an excellent 5-Part Series on barrel chambering. The Series, entitled The Voyeur’s Guide to Barrel Chambering, is not intended to be a “how-to” instructional treatise for gunsmiths. Instead, German’s 5-Part Guide is aimed at the end user — the shooter. German explains: “This Series isn’t intended for anyone who owns a lathe; instead it is for those of us who send an action off to get a new barrel installed. Those who have the equipment know what to do and how to do it and I have nothing to teach them. On the other hand, if you’ve ever wondered just what goes into barrel fitting, this is it.”
PART I | PART II | PART III | PART IV | PART V

With well-written text and dozens of very high-quality images, German takes you through the chambering, threading, shoulder-fitting, and crowning processes from start to finish. The idea is to give the “barrel consumer” a clear idea of the processes involved when a barrel blank is converted into functional form, complete with chamber, threaded tenon, fitted breech, and crown.

We highly recommend German’s 5-Part Voyeur’s Guide to Barrel Chambering. German, with the aid of John Lowther (who ran the machines), did a great job. The series has already drawn much attention from our Forum members, along with praise. After reading the articles, John C. from Australia wrote: “Your Chambering articles… really are excellent [and] informative for those of us too scared to watch our gunsmith chamber one of our barrels lest we distract him at a crucial moment!”

We know you’ll learn something from reading through German’s 5-Part Series. And if you see a photo on German’s website that intrigues you, simply click on it to see a larger, higher-resolution version. All the images in the Voyeur Series on RiflemansJournal.com can be zoomed to larger formats.

Dan Lilja Now Offers Pre-threaded Barrel Option ($30 Extra)

Lilja Rifle Barrels prethreadedDan Lilja of Lilja Barrels has announced that, starting this month (June), his company will offer a pre-threading option for in-stock and made-to-order Lilja barrels. The price for the threading option is $30 per barrel. The first offerings will be for Rem 700 actions, and Lilja will, later on, offer pre-chambered barrels as well. Dan tells us: “To begin with we are threading for the Remington 700 actions. Other action types will be added in the future. And we are also planning to offer chambering along with the threading for a limited number of cartridges in the near future.”

Details of Pre-Threaded Barrels — Gunsmithing Still Required
Pre-Threading will only be offered, initially, on 28″ or 30″ blanks (length prior to threading). The barrel will NOT be finish-crowned, and Lilja does not offer muzzle threading except for drop-in AR-type barrels. Dan points out that his pre-threaded barrels are not ready to install: “The barrels will still require a gunsmith, experienced at fitting barrels to actions, to make the final fitting and headspacing adjustments on a lathe and using headspace gauges. Lilja will turn these threads for the nominal dimensions for the action type. But action makers have tolerances and other operations such as truing an action face or bolt or lapping bolt lugs can change dimensions enough that headspace or thread shank length may need to be modified.”

Basic Gunsmithing Videos from MidwayUSA

Larry Potterfield, owner and founder of MidwayUSA, has created some basic gunsmithing videos that are worth watching. These show some key aspects of rifle metal-working, such as crowning a barrel. Be aware that these videos are really just teasers — they don’t illustrate most of the critical preparatory steps a skilled gunsmith will do, such as leveling his lathe precisely, and indicating the barrel very, very carefully. Nonetheless, there are some good, basic tips in the videos, which should be informative for all shooters, whether they do their own smithing or not. Please note that benchrest smiths may employ more advanced methods.
