Master riflesmith Geoff Montgomery from Wyoming Gun Company walks us through his process of how he fits and chambers a barrel to a Defiance “Anti” action for an extreme lightweight precision hunting rifle. Demonstrating his process of checking aspects of the components and centering the super short 18-inch proof research barrel in the lathe for machining of breech features and precise fitment of the receiver to the barrel. This ensures everything is concentric to the centerline of the barrel’s bore to guarantee a precision rifle build. Geoff shows you how he uses measurements from the custom receiver and bolt to determine the correct fitting and chambering dimensions of the cartridge with headspace gauges for a 6.5 PRC cartridge. He then moves to the muzzle end, demonstrating the techniques for finishing up that end, complete with a flat/60-degree crown and ⅝-24 threads for a suppressor adapter, and the challenges associated with a short barrel such as this. Once machining is done, Geoff shows torquing the barrel, checking headspace, and ensuring a “match” or “tight” chamber well within safe limitations while preventing unwanted case stretching.

Weight comes in at 3 pounds 2 oz (roughly) as-is. Once completed, this extremely lightweight-high, precision hunting rifle build will perform incredibly well while being as lightweight as possible.
