Anyone know of anyone who has any? Ive checked with jamison and Quality.
 
Thanks but the ones I'm looking for are the ones based on the 378 case
 
????? HUH??...a 338 A Sq ( or also know as 338-06) is a 338 caliber BASED ON a 30-06 CASING..?? If you have a 338 caliber based on a 378 casing...then you DONT HAVE a 338-06??

338 A square magnum cases could made out of 338-378 cases Im pretty sure .
Then A square developed there newer case the 338 Excalibur a bigger case with no belt.
 
I see that THERE IS a cartridge made up with a 378 Weatherby casing....but it is called a 338-378 cartridge..NOT a 338-06

Thanks for the replies... but... i never said i have a 338-06. I have a 338 a square and the parent brass is the 378 weatherby. And no its not the 338/378 weatherby.

And what CALIBER is it then? You are talking about a cartridge made by the A-Square company lots difference evidently that the cartride referred to as a 338A Square wich IS a 338-06.
 
It's a 338 a square. It was developed long before the 338-3006. Art Alphin the founder of a square developed it even before there was a 338-378 weatherby. It's a 378 weatherby case with a tapered shoulder and necked down to 338 , not the weatherby radius.

Since it says the company of A Square went under in 2012....you'll have to make these odball casings from th mother ship...which I think..??...is the 416 rigby...and size them / neck them down
 
There is a few brass companies that make them but no one has any stock. I may end up rechambered
 
FALSE-A-MUNDO! A 375 case....sure...but not a 378 case!
Do a search on it this is what you will find........RIGHT- A - MUNDO....

The .338 A-Square is based on a necked-down .378 Weatherby belted magnum case with a conventional (not double radius) shoulder angle of 35 degrees and a cartridge overall length (COL) of 3.67". The .338 Excaliber is based on a standard (not belted) rimless bottleneck case with the same rim diameter as the .378 Weatherby, but slightly greater powder capacity than the .338 A-Square or .338-378 Weatherby. The COL of the .338 Excaliber is 3.75".
