I don’t, generally, have to re-zero rifles from scratch. But when I do, doing it on a Blaser is pretty easy. From the clear line of sight through the barrel, to the easily removable bolt, and even a rear-monopod all align to make things simple.
And as far as I can recall, this is the only time I use the rear monopod. Zeroing.
