Thanks for the pics and for all the information. Really great stuff!

Glad to see the .416 Barnes size down ok. Certainly opens some options. Was just looking at some .416 Hammers and could be some good choices there. I think I am going to be glad I bought bullet resizing dies.

Anybody done any terminal tests with the 400 grain Hornady RN?

I have actually seen them pretty regular on GB. Not cheap but at least available.
