Thanks Stimpy, good thing I asked, I had about decided to do it the wrong way.
I'm working on getting my Handi flyweight 243 barrel to shoot again. It is horribly inconsistent. One day it will shoot pretty good, the next day the same load couldn't hit a watermellon at 100. Then I got to looking harder at my brass. I have had some of it for years, and others are once fired. So it is time to give it some TLC.
