[QUOTE="statjunk, post: 373064, member: 18873"] Ok did another experiment today. I took to pieces of fire formed brass. I measured them with the mic and they are .002 over saami. I put one in the ram and sent it to the top. I started the FL die down onto the brass and it stopped. I lowered the ram and dialed the die down a very small amount. Operated the ram sending the brass into the die and it met almost no resistance. I measured the brass with the mic and no change. I did this over and over and over again moving the die in small increments and I didn't see any change whatsoever. I continued to make sure that the die wouldn't hand tighten down onto the brass at any point as though it were hung up on something. At some point I could see the mark on the brass where the die was neck sizing it. So I pulled out the neck sizer and sized the brass removing the old primer. I put the brass back on the press and operated it again in small increments. It wasn't until the bottom of the die was even with the underside of the press that I saw a change and the brass started to get longer. The mic indicated that the brass was .003 over saami. As I dialed the die down it just kept getting longer, .004 and .005. It wasn't until the die hit the shell holder that it made a change and it went all the way down to -.004 under saami. So there was a .008 change in the size of the brass. I was like ***. So I took the other piece of fire formed brass, that hadn't been in the press and measured it again, just to cover my arse. It was .002 over saami. I sent into the press expecting it to be -.004 under saami and to my surprise there was no change. Still .002 over saami. I just stopped right there. Does anyone know what is going on with my set up? Are my dies not set up properly? Thanks Tom [/QUOTE]
