Thanks John. You are so right. I was just concerned about printing it because it was copyrighted.

The bad thing is, if you try this same test with a completely different load, in say 16 gauge. Those primers will be in different locations. I've tested enough loads to know that they will act differently in different loads. Sure, you're magnum primers will always be at the top. But the others will move around. If you're not following a specific tested load, the only way you'll know for sure how a primer swap will change the load, is to have it tested.

Thanks for the info Dave. Interesting stuff..About the only primers I interchange are Remington 209 for Winchester 209.They are pretty much all I use.
