There's no such thing as a real "deer rifle" here, but since all big game is similar in size, it's usually all hunted with the same gun.
A good 65% of those are made up of Blaser R8s and R93s, the other classic Euro bolt actions like the Sauer 202 and old Mauser Sporters. Either .30-06, .308, 7x64 or 8x57
Another 25% are combined guns, most often O/U shotgun/rifle combos or the classic Drilling with an "Einstecklauf" in a smaller caliber. These days often 12 or 20ga with an 8x57JRS, 7x65r or a .30-06 in the main rifle barrel.
The rest is made up mostly of semi-auto hunting rifles like the Sauer 303, Merkel SR1 or Browning BAR. There are almost no levers or pumps to be found, their owners always gather a lot of attention during the winter drive hunting season.
As for scopes, most guns you'll find with either a 2,5-10x50 or a 3-12x56 as a main optic, almost exclusively for the reason of light transmission during wild boar night hunting. Iron sights are always on the gun, but almost never used.
I nearly forgot to describe the area with all this gun talk going on. It's basically a mix of farmland and forest used for logging. The fields average 80 acres at the very most, often smaller. The forest is a mix of beech, oak and (douglas) fir.
If you wanted you could probably shoot out to 500yds in the daytime, but almost everyone limits their shots to 200yds maximum. Most of the hunting is done from permanent stands and blinds.
