Help, .375 A-square

[devildoc]

So, my brother wants to build up a .375 and he asked me to check into the .375 A-Square. Problem is I can't find much of anything about the cartridge. No cartridge drawings, capacity, parent case....nothing. Anybody have any info about this. I'm thinkin' it might be a bad Idea at this point, cause if I can't find any info about it, getting a reamer may be a struggle. Anyway, any help is appreciated.

It is a 378 Wby with the case shortened slightly and the shoulder moved forward slightly, It also has a 35 degree shoulder instead of the double radius of the Weatherby. No real advantage over the Weatherby.
