another update ...............
the PT&G reamer print has been updated and Manson has been sent the JGS reamer print.......
I'm also releasing the 375 Warlord ll ....
basically the same case minus the belt, PT&G will have a bore rider /stepped throat reamer available to order soon as I confirm the dimensions are all good on print, JGS and Manson will have the 375 Warlord ll as well but with a conventional throat, the belts on the 585 HE can be easily turned off via a cutting device similar to a neck turner attached to a mini lathe and I will see if it can be converted for use with a cordless drill, the 375 Warlord ll can also use the 375 CheyTac long brass, this route is even simpler to make brass with, trim the neck down, push shoulder down until bolt closes, load and fire, since the neck is already 375 cal you won't need $800 worth of case forming dies and just use the FL reloading die to push shoulder down, Bruce Bertram makes this brass super tough

For comparison...for the folks that are always looing for more.
From the left - .338 Big Baer (basically a .375 CT necked down to .338), .416 Barrett, .400/.50 BMG, .50 BMG, .50/20 variant. The .400/.50 BMG runs 480 gr custom coppers at almost 3300 from a 45" barrel. The .50/20 variant runs 800 gr solids at 4200 (forty-two hundred) from a 45" barrel - without pressure signs.
