Good question. I had a look on Midway and there is only Bertram (soft) brass at $80.00 for 20 - ouch!

If (and that's a big if) I were to ream my sweet 1978 1-H .458 WM, it would be the Lott.

Why?

a) You can still shoot a .458 WM without worry.
b) Good availability of ammo and Horandy brass.

However, I have no plans as I like it just the way it is.
