I do prefer my kipplauf to be short, my 20" 30/06 barrel is much handier then my 24" hornet barrel. I know it's only 4" but it makes a difference to me, I'm actually considering having it chopped.
But seeing as the 20" is a Stutzen and the 24" regular the weight is about the same and so is the balance.
It's more using it from a vehicle or pushing through thick country where that 4" makes a difference and the hornet isn't used for that sort of thing so the little extra velocity is possibly advantage enough to keep it unmolested.

But I can't look at the Fanzoj guns, they always leave me looking at my savings and trying to work out the logistics of importing one.
