I have the Swaro Z5 3.5-18 BRH on my .340 Weatherby. It's solid and needs no adjustments after sighting in at home then confirming zero when I get up to elk country. This last season, I was side hilling trying to catch up to my guide who had the tripod set up on a bull across the canyon. Paying more attention to the bull than where I was stepping I slipped on a log that was hidden in foot tall grass and fell on my rifle and twisted my ankle. I fell so hard that I bent the Swarovski aluminum objective cover and it wouldn't open. When I caught up to the guide, I was able to open the objective cover, chamber a round and shoot the bull at 242 yards.
When I got home the next week I shot the rifle, and it was still spot on two inches high at 100, shooting a .70 group. I don't read much good about Swarovski on the forums and it appears there is not much love for them. I love mine and would replace it with the same if I need to eventually.
