From the 9th edition of the Hornady manual...


Cartridge ............ Max Brass ..... Max COL

30-06 ..................... 2.494 ........ 3.340
308 Norma Mag ....... 2.559 ........ 3.345
300 Win Mag ........... 2.620 ........ 3.340
338 Win Mag ........... 2.500 ........ 3.340
30/338 Win Mag ...... 2.500 .........3.340


The 30/338 Win Mag is not in the Hornady manual. I am just assuming that the wildcat 30-338 Win Mag will match the factory 338 Win Mag.

I do not know if the brass length is a deciding factor in the Super 1050 or if it is only the COL.
