I can think of no reasons a Mannlicher stock or a fixed 2x would be choice with today's options.
I bought this Ruger Hawkeye RSI .308 this year. It has a fixed 3x with a heavy duplex. My load is 150gr RN bullets over Varget. It's light, handy, and points naturally.
About perfect IMO.
You simply have to shoot an 18" Mannlicher stocked rifle to recognize how badly the handling of short-barreled conventional stocked rifles fails.
The Mannlicher carbine handles and points naturally, and a low-powered scope offers the wide field of view needed for close-in shots.
And in 308, the blood trails are easy to follow through the dense brush.
