I forgot to mention that I have never had a scope failure yet.. (knock on wood). I shot my guns year round and like I said the 1100 is well over 20 years old. they all have 100's of shots through them. Yes it is an expensive hobby lol but I have to have somethign to do during the off season. But like I was aying all the scopes have held up wonderfully. MOst of the time I find if I only use one during season and dont pick it up until close to season again they do not need any adjustments only every once in awhile and it is usually very minute like two or three clicks.
