I worked up some loads and settled into a load of 2.7gr of Unique with Hornady 71gr .311 FMJ. The brass is 100 brand new Magtec, ("CBC" head stamp) with about 100 or so, other brand range pick ups. Now to the problem.
I have noticed I can press the bullet into the Remington brass with my fingers, light neck tension, very light on some. Now only the rem brass seems to do this, all other brands (FC, CBC, GFL, MRP) have good neck tension and don't set back any. Is there a known problem with Remington 32acp brass or is it the lee dies? Not all rem brass does this, but most, id say 90%
The seating die is set to just take out the very light bell of the case, as I do with 9mm and 45acp dies. After I found the problem brass I pulled them and resized and tried again with a bit more crimp. It took a heavy crimp to keep the bullets from setting back. It actually rings the bullets it's so heavy, and the bullets spin in place. I learned long ago that is to heavy. So whats the deal?
