The shotgun barrels are 16 and 16 but the rifle barrel is 10.75x65R Collath . I use a 207 grain cast gas check bullet sized to .429" and pushed with about 16 grains of SR4756 .
To make brass for the cartridge I took Hornady 405 WIN brass cut it down to length ran the case partially in a 444 sizing die . I also had to turn the rim diameter and thickness on our lathe . But after all that I was finally able to get it to shoot decently at 50 yards with the irons .
