@ endophobic:
Your Aussie rifle; is that an 8mm on a .303 case?
Original rifling pitch on German rifles remained unchanged through the 98 period, and they used (in order) 227, 154, 196 and 178-grain slugs. The 178s were iron-cored and had the profile of the 196: boat-tailed. The 227 and the 154 both were flatbase bullets.
I have had good shooting from Mausers with the 150 Hornady and also with the standard US 170/175-grain bullets.
You will really need to determine the rifling pitch of your rifle in order to 'suss out' the ideal projectile weight. Original Gew 98 spec was 1 turn in 9.39 inches, this according to TEXT BOOK OF SMALL ARMS - 1909. I would suggest starting with a 170.
Hope this helps.
