I had a Buckmasters 3x9x40 scope mounted and laser bore sighted on my 336C by a gunsmith who I have used for years and has mounted several scopes in the past for me. This time something must have been off because it took me 40 clicks to the left and 40 down just to get it on paper. I was shooting at the center of a 4' x 2' silehoutte target at 100 yards and could not hit it. Once I got it on paper it took me another 20 down and ten left to get it where it should have been when I started.
I did some reading tonight to learn what is happening when a scope is adjusted for elevation and windage. The erector tube is what is moved during the zeroing process if I understood the article correctly, so my erector tube must be severely off center and at an extreme upward angle in relation to the reticle. I'm assuming the reticle is always stationary. Also, it is possible to break the erector spring with that much adjustment?
Has my scope been adjusted so much that I need to have it reset to factory settings and bore sighted again? Of course, I don't know how I would put it back to factory settings at this point. I did not make a note of the adjustments once I got it in the general area and I was changing bullet weights and having to make adjustments for those changes as well.
