A lot of these are coming onto the market from germany. A lot of their hunting for boar is done from highseats at night under the moon and they are all using the latest generation of 56mm zooms from Zeiss, Swarovski etc. They are inundated with boar and pressure is on to shoot numbers. With these old drillings the cost of having new rings fitted to take a new scope is several hundred Euro so they are trading these in for the latest Blaser R8s all fitted with big scopes.

That looks a nice drilling. Those Nickel scopes are good but the reticle will move as its adjusted and field of view will not be as wide as modern scope. I have an old Nickel 1-4x20 scope and even at 1x, my swaro Habicht 4-12x50 has a wider field of view at 4x than it does.

7x57r will do everything that the 7x57 will do. Most ammo is loaded to slightly lower pressures so it's probably 20 yards less effective - i.e. It will perform at 80 like a 7x57 will at 100 - in othersclose enough that it's not important. 7x57 is a very efficient deer cartridge that will also perform well on other game given the correct bullet and bullet placement.
