Please take Jeff's advice and only use the OAL gage from hornady that measures the base to the ogive of the bullet. This is the only true meaningful measurement that you can use with repeatable performance. This has to be done with every bullet brand, design, and weight. I also do it with every lot change just to ensure lot to lot variances are accounted for.

Thanks for the help and suggestions. This is what I will be doing in the future as soon as I get the tool! Thanks

Jeff,

What about for your prepped brass? What tolerance do you try to hold?

I let it go about .005" to .010" over my trim length. Usually I like to keep them all within .005" of each other.
