270 Titus also known as 270 Savage.
This is basically a 300 Savage necked down to 270
Handloaders Manual of Cartridge Conversions reccomends reforming 270 Win as there is not sufficient support for the neck when reforming 300 Savage. This cartridge will make a 130gr bullet go 2763 fps according to Ackley. This was a not very common conversion done to some 99s.
Do you know how old/what model of 99 your friend has ?
