[QUOTE="Trickymissfit, post: 481887, member: 25383"] sounds like a 416 barrel runs parallel with a 4350 or a 4320 carbon steel blank. 47RC is about it with these steels, but you can of course run it thru a nitride process. I'd often simply use something like 4150 or 4350 pretreat steel, and the run it thru a nitride process afterwards (these pretreat steels come with a hardness of 28 - 32RC, and if you buy a good brand they are very stable). I have taken steels like 4340 and 4350, and hardened them to their max, then nitrided them. One problem with a lot of alloys is that if you harden them to their max is that they actually become a harmonic nightmare. But you don't see nearly as much with a hard shell on it, while be a little softer in the middle. One thing that has always been in my mind with the idea of adding a hard case to a barrel is flex. It would seem to me that a hard case on the exteriors of the steel will increase rigidity; which is a very good idea gary [/QUOTE]
