For the money you have available, maybe a few quid more, look for a second hand S&B 6x42, good optics, all the magnification you need and will last several lifetimes. I have shot beasts in the forest with them and out on open ground, have fallen flat on my rifle landing on the scope, no shift in zero. Zero it in an inch or so at 100 yards and you can just point and shoot out to the 200 mark, no fiddling with magnification could not be more simple, I have had one for years and love it.
