Rooikat LCT-30/ZT3

would use the same rounds I believe

Wouldn’t get the du rounds tho

Dont even know if the rounds for the bushmaster 30 has anything else…

It’ll prob use MK258

can penetrate < 100 mm of Rolled Homogeneous Armor (RHA) at 1000 m

This I got from Badger - Tank Encyclopedia
and this seems to be fairly reliable as many books and websites say something similar (with differences being mostly range stated)

Edit: so having just checked in-game the stat card of MK258, I can see that IRL and in-game the Badger would most likely use MK258 as the stats are very similar between what the Army says and MK258 in WT
