Curious why you chose a 308 ? For easy ammo availability ? Do you reload ? I suppose that there are few modern bullet choices in 7.5mm for the original Swiss cartridge (7.5x55), but a 6.5x55 or 6.5x284 or 7mm Rem Mag might have been better choices from a performance standpoint. If the 308 is for training, then it certainly is effective, since it has a lot of drop and needs good wind correction technique.
I used to fly ZA to Basel for a few years and did get to explore a little. The small villages are picture perfect. Zurich is a big city like most big cities = traffic jam... Very polite people at the borders but who take their job very seriously.
The Swiss have succeeded in keeping their federal government an appropriate size and seem to have avoided the abuse of power that the Americans are experiencing with a Federal government out of control. A working vs a dysfunctional Federation... We could learn a lot from you guys...
