A friend of mine inherited a bound Winchester feasibility study from an uncle. The title page is stamped “Corporation Confidential.” The study is titled “Cold Forward Extrusion of Rimfire, Centerfire, and Shotgun Barrel Blanks.”

Anybody heard of this study, or aware of this report existing elsewhere?

Also, please let me know if this is posted in an incorrect forum.

Sounds like an engineering study, a few here would probably be able to understand it. Sounds like button rifling but I’m probably wrong, as usual.

I think they were looking at sizing barrels though a die or  hammer forging the rifling as opposed to cutting it. 

Extrusion – The slow forcing of material under high pressure through a die to reduce its diameter. This process is generally performed in a hydraulic press. Lead wire used in bullet making is extruded. A subset of extrusion is impact extrusion. Impact extrusion uses a fast strong blow rather than slow pressure to form a metal part with an internal arbor or in a closed-bottom mold. 

But I’m not an engineer and I didn’t stay at a motel lately.
