[QUOTE="Buffalobob, post: 152252, member: 8"] This thread actually turned out to be very useful. I was getting my 240 Wby brass ready for reloading. It had seen some pretty fierce pressures (at least as bad as what Wildcat does and then some). I deprimed, neck sized, trimmed, cleaned the primer pockets and then tumbled it. After that, I took and ran each empty case through the action and about half of them were so big that I had to force the bolt down and closed. So I sorted out the ones that were just fine and took the ones that were too big and full length sized them in a RCBS die. They were still too big. So I got out my calipers and started measuring stuff. Of course my calipers are so old they were first used by Copernicus and are not so accurate. Nonetheless, it was clear that the belt diameter was too large and the case in front of the belt was too large and maybe the shoulder was too far forward. So after about an hour of trying to measure the distance from the shellholder base to the edge of the belt groove inside the die I gave that up as a useless effort. This particular thread came to my mind and so I pondered how a machinist would cut a few thou off the bottom of a die and decided that didn’t matter what a machinist would do because I would just have to make do with what I had at hand. So I went out to the garage and started looking around. My belt sander caught my attention and the rusty gears in my feeble mind started cranking around and pretty soon I had the sander plugged in and turned up side down and was just sanding the fool off the bottom of the die. So when my experienced eyeball said I had removed a few thou I rinsed it out and slapped it in the press and what do you know, but it sized those cases right down to where you would not even know a case was in the chamber when you closed the bolt. Of course the excessive pressures the cases had seen caused the primer pockets to enlarge and so I lost 6 out of the 40 but I still was 34 to the good. [/QUOTE]
