Head space comparator gage
#13
rd, Thanks for the tip on annealing.  These cases are brand new but I will be sure and do my older ones.

What method do you use to anneal the neck and make sure you don't affect the body and case head?

As a further FYI here are a couple of pictures from some of my old Shooting Times magazines that show more clearly what I was trying to explain yesterday.  If you click on the picture I think you will be able to read the notes easily.

Here is a cutaway .30 Herrett barrel and chamber showing how a rimmed case can be head spaced on the shoulder.

   

And here is a picture of a sectioned .218 Bee case showing that a few thousandths of clearance at the front of the rim will still leave plenty of "meat" to withstand the pressure (same as the Herrett).

   

I will keep you all posted on my work with this pistol and hopefully next week I'll have some good targets to post!
