How do you folks square your scope to your rifle?
As you can see I go for the "bubble method", but this is only recently.
Before, I used to fit the scope loose and mount to shoulder and adjust till it looked upright and then tighten down the rings gently and check again.
I always try to keep the gap in the rings equal but it does not always turn out that way as if you pull down a fraction too much one side it always moves the scope, reticle not straight
With this method it seems to be "almost" right.
I was once told by a rifle smith that everyones shoulder sockets are different hence the reason when you shoulder another persons rifle the reticle looks on the p***
Whats your "foolproof method".
Apologies if this has been done to death before
