Re: Best oal gauge?

What is this about having to calculate in head space when using a Hornady/Stoneypoint style OAL gauge? Brad

    here's some thought I picked up from the benchrest crowd years back:

    The case neck is over size in the I.D., but the basic body is slightly undersized. I personally prefer to do it all with once fired and unsized cases to calculate the headspace. Theye will then glue a shim to the face of the case body to get the proper headspace off the modified case. This can be measured by compairing the modified case with a once fired case. Most of the time it's about .0025".

    Now I don't worry too much about this. I make my deminsions off the fired case, and know the difference before hand. So when I measure the bullet in the mod case I simply add the difference between the fired and modded case. Not perfect, but very close.
