[QUOTE="Memberberries, post: 1755273, member: 106647"] It's all in the tools you use. From what I can find the ones from STAG are 4140 or 4150 just like their barrels. you can see from the chart that 4150 is maxed out in the 50's for hardness and realistically they probably bring it back down into the 30's for toughness. At work we use cutters, not grinders, on prehard material like A2 that is up into the 60's without any problems. you can't use HSS cutters on that hard of materials just like you can't use your average hardware store files on something in the 50's. A piece of bar stock and lapping compound will do wonders where normal files tap out. [/QUOTE]
