Mart, I'll have to "second" the Herter's .401 Powermag! Waiting on some ammo to shoot the one I recently acquired!

I found a 150 rounds of brass and a set of CH4D dies for mine. I have also been making cases from new Starline 41 mag using a 40 S&W die to start and a 7/8-14 bolt bored and reamed to .426 to finish the cases to the rim. Time consuming but cases are hard to find and expensive if you do find them.
I have all three of the Powermags, 357, 401 and 44. Strong and very well made guns.
