"It might be that my countrymen are generally pragmatic when it comes to shooting, and all such rifles in Australia have already been modified as required to shoot to the sights."

Spot on.

Why own a DR that doesn't shoot to the sights - as you know, when things happen you need it to "Point, Shoot and Hit" without worrying over having to remember where to hold.

And as for "anglophilic shooting mates" that's the best alternative to "Pommie bastard" I've heard in a long time !!!
