btw, the 470 mbogo is from 3" propritary brass, and in order to make it correctly, must be made from this. you CAN make it from rigby basic, but it's a hair short.

Hmm.. if the 416 bell brass holds up as well as lapua, thats a very nice thing.
Also, I see him offering the accurate reloading wildcats. 416 AR, wich is the ballistic twin of the rigby, but does it in the standard remington action. 375 Rum cut down to 2.65 and necked up. Does 2450fps with moderate pressure. Which would be cool, if its better then remington brass!

If you want more information on theA.R rounds, the 416 AR, 458 AR, and 470 AR, you can follow this link to my site
Or even more data on the 550 express or 550 magnum.
Some pics, some interesting things
These are ~4% more capacity than the 416 rem, 458 Lott, and 470 Capstick.
These are designed to be the largest, biggest, baddest, and frankly, with the 470, the coolest thing you can put in a standard length action.
CH4D makes dies
Jamison will sooner or later be making headstamped brass.
you can order a reamer from Manson, or, for about the price of a reamer and headspace gage, I can point you to a gunsmith that will do that for you.
416 AR should be able to break 2500 FPS... if you believe a taylor can hit 2400 with a 400gr, then what can you do with an additional 17gr?
The 470 can push 500gr woodleighs to 2400, but why? the last 100fps is all ego and PRESSURE!!!
anyway, here's a pic of the rounds.. pics of some of the built guns are on my sights...
this is no "paper designed, but not made" wildcat
