This is a 25-06 and it is obvious when looking at new and 1x brass there is a huge diffrent in angle of shoulder. I am using a redding full length s bushing die with expander removed. I am using an RCBS #3 case holder in a Rockchucker press and winchester brass. The die is set in the press deep enough to get a good but not to stiff cam over when the press is fully raised, just as you might have it when sizing virgin brass.The once fired brass before being resized measures between 2.032 and 2.034 using the hornady head space gauge. The brass is lubed and run through the die then wiped of and remeasured The head space does not change when checked. Still in the 2.032 to 2.034 range. Putting the brass in the chamber makes for a little bit of stiff bolt but not terrible. The cases length when virgin was trimmed to 2.484 using the sinclair/wilson micro-trimmer after one firing they have grown to an average of 2.491 I am working 89 rounds and they all show the same appx. measurments, so this is a goodly amount to show and not an anomaly. I also have an RCBS FL sizing die and it is also set with a cam over for virgin brass when using it the results of head space are the same. Lets hear yals thoughts. Brad
I think you are pushing your shoulders back to far causing a bulge at the wall shoulder juction.
Do what ( dbhostler) says. I have competition shell holder sets but you can do it with feeler guages.Run the ram up and put a .012 feeler guage between the shell holder and screw the die down to it. Try it in the gun go in .002 incurments till the bolt drops easy with out the firing pin in it. You won't get a go feel unless the firing pin is out.
