JustC...could you explain this in more detail...
quote:You can examine the headspace issue very quickly with cheap tools. The Stoney Point comparator or the sinclair comparator used to measure before and after lengths to the datum line when firing as well as when sizing. I have been using the comparator for a while now, to set the FL die to PFL size and just pull my shoulder ahead by .002" when sizing. That forces the compressed fit to help eliminate overworking the cases and stops casehead seperations before they primer pockets are trashed. The comparators are some of the most helpful and cheapest things you can put on your bench to give you the "quick and dirty" look at just what your dies and your chamber are doing.
I too, use the Stoney Point comparator...but I only use it to measure seating depth of my bullets. How can you use it to measure before and after lengths to the datum line? ...and how do you use it to set up your dies? The only possible use I have been able to figure out is to help with bullet seating b/c it enables you to measure to the ogive on the bullet. Perhaps you could take a minute and educate me on the matter...[^] Thanks![:)]

Eric,..you caught me slipping on that one. I meant to say the Headspace tool (had been working with a comparator earlier this morning[B)]) I meant the headspace tool,..it's cheap and easy to use. best part is you can buy 2 sets and use them to measure bearing surface lengths[;)] 0 -
