I didn't read any bad mouthing of product bashing going on mate, just a few questions about what appears to be a scope playing up.
I had a Leupold 40X give me problems and said so here, asking advice on what a scope failure looked like in terms of the groups. Everybody was very helpful and polite because it is common knowledge that making Leupold LCS's reliable can at times be a problem. Seems like Nightforce scopes have a more loyal and vocal following here !!
The guys here talk about scope problems, pulling them apart, altering them and even gluing the internals solid all the time, I fail to see what issue anybody could take with your question or subsequent posts. Saying that they have a Leupold that failed and who is the best guy to glue the insides up is more of a criticism of the product than you made !!!
I'd read down to about post 8 and ignore what was said thereafter !!!
I think they "read into" your post things that you didn't say or mean rather than take the literal meaning of what you actually typed.
Don't sweat it ............
On a more practical note. I'd doubt that a scope that was shooting good groups would suddenly not return to a proper zero by 4 inches. Sounds dumb but I'd check and double check that you returned to the proper setting. Did you make an adjustment at 600 and reset the dial or something. I'd have to imagine something simple is more likely than a scope problem.
