Both of mine like the heavier bullets pushed with full loads, like 195 to 200 gr at 2,500 fps from the carbine, and 2,600 from the Mauser rifle ( same load ).
The will (has) killed large deer stone dead on their feet, shot through 450 lb boar like they were warm butter, and lengthwise through all but the last 8 inches of haunch in a grizzly bear ( for the owner of my former 22F).
A .30-06 will do all that, and more, from a 24-inch barrel, but the larger 8mm bore is more efficient from the carbine.
And every old Mannlicher needs a stable mate.
