Cryo treating relieves stress in the metal, and will help a barrel that is loosing zero as it gets hot from repeated shots (I've had it done to a few rifles. WORKS!) I didnt find anything about forging type, or any description of their machining at all. I'm surprised, usually thats a bragging point for companies. For as rough as the machining on the rest of the rifle is, I have to say. The chamber and bore of this rifle are likely the best I've seen. Really starting to take on a shine with all the cleaning. Glistens like a mirror inside so much its hard to focus your eyes on to inspect, hard to explain without seeing it (I'll try to get a picture tommarow).
After each cleaning all but the last three patches turn green after laying on the floor a while (copper residue), & Winchester Supreme is some DIRTY shootin stuff! LOTS of powder residue in the barrel after each shot.
When I first took the rifle apart it looked really clean. But inside the Accu-trigger housing I found about half a teaspoon of what I think was polishing compound. It wasnt grease, I rubbed it between two fingers and it felt like toothpast, NOT slippery at all. Though the saftey lever did have a little yellow grease on it inside. If you own a Savage make sure you take the trigger apart and inspect for this stuff! It's grey. I wouldnt have found it if I didnt take the trigger apart to do a little deburring and polishing.
