Nightforce problem or cold weather

[galold]

I just got back from the range and had a problem with my Night force scope. My 6BR is zeroed at 200 yards. After clicking up to 600 yards shooting, then clicking back down to 200 yards,the exact number of clicks) My point of impact was about 6 inches lower. The temperature here this morning was 33 degrees, but would that effect the scope? Has anybody experienced this before?

If you zeroed that morning at 200, and then clicked to 600, and then back down again it should still be on 200. If it's off by 6" your scope is broken it's not the temperature. Just send it back to Nightforce they have great service.

However if you established your zero last summer when it was 90 degrees don't expect it to be on now when it's 33 degrees. Your going to need to add a few clicks.
