Pat,

I was counting on the data that I have and maintain in Quickload for OAL and then just recording the changes. This ..... varries since the bullet engraves on the olgive (when not choking) which does not get changed by any sizing method. It also will lengthen simply when the angle of the rifling becomes less which is inevitable. So I made cerrosafe casts to monitor the ball seat or free bore as some people call it for errosion. And diameter as well.

It should also be noted that my shooting style is slow and the barrel temperature is monitored and babied for group testing. All cleaning is with guides. No abuse takes place .... ever. I'll see where this goes.
