well i was just wondering b/c i've been working with some 5160 that the guy i got it from said was annealed but i've been having a LOT of trouble with it, like wearing down hacksaws and stuff but today i was working with some mild steel and used a drill bit that i'd used on the 5160 earlier and had a lot of trouble with it chipping and screaming and breaking but with the mild steel it went right through it, and so i finally realized i might not be a moron after all! so i was just checking to see if it should be softer which it sounds like it might be, what about 5160?
