[QUOTE="4mesh063, post: 26339, member: 941"] CatShooter, First, I like my cats! [img]images/icons/smile.gif[/img] I did a test on the red hot and quench deal but since there didn't seem to be any interest, I just emailed the results to anyone who was interestes. As for pictures , I borrowed a camera and got a photo of it while it was unfinished and I'll send it to ya in the mail. I have no place to post the photo. I took the same body brass that rockwelled in the 80's can't remember now how high exactly, and got it red hot. Left 1 piece air cool and 1 I quenched. I also did a neck for the 2 seconds and quenched it. the pieces that were red hot were so soft they could not be read on the tester I have. They were like butter. Air cooled or quenched. The 2 second neck stopped at sixty something so that leads me to believe that quenching stops the process as well as makes the final hardness a random number. I don't like the dead soft stuff, so I have decided to continue doing the 1.5 second heat thing. If it's wrong, it won't affect anyone elses gun even a little bit. If quenching stopped at 65 lets say and air cooling stops at about 35, then the amount of time between heat to quench is very important for consistant neck tension and neck size. There's a big difference in how much rebound you get when sizing depending on how hard the brass is, as you probably know. [/QUOTE]
