Scope Zero Question?

Lost me!!

If the scope isn't exactly optically centred, (and most aren't,) when you rotate the scope in the rings, you will get a "smiley." This doesn't mean there's anything wrong. Do a search on "optically centreing your scope."
If you're only an inch out, I don't see how you can't "twiddle the knobs."
If its a .177, zero at 15 yards, then it should be close at 35, so fine tune at 35 yds. If its a .22, make it 30yds.

I could just twiddle the knobs...BUT..because it's off to the right at 10yrds and off to the left at 25yrds, I can fix one but not both by zeroing with the turrets.

Optical centering was the way I was thinking of going, Just didn't want to waste my time doing something unnecessary.

With regards to getting the scope level, I have various vertical bits of string and rope round the garden, courtisy of my kids, which tells me when the reticule is vertical....however I haven't quite managed to work out when the rifle is vertical/horizontal, also do I need to worry about the front to back level, and if so do I do this with the scope out....it's a 50mm so the front is taller than the back, so I can't put a level along it.

If anyone has optically centred their scope, I guess by shims (film neg or bits of metal. I am still unsure wether to shim the rings, and risk putting stress on the scope tube, or to shim the dovetails......


Time for bed now.
Hope to pick this up again at 05:00
