How to level rifle before leveling scope

[chizelhead]

Another system is the Wheeler leveling kit. I set my rifle in the cleaning stand to level. A vise would work as well.

I use the wheeler leveling kit and a plumb Bob. I attach a bubble level to my scope during this time too. Must be how I shouldn't a rifle or slightly to low of rings but I swear my reticle is always canted when everything is "level".

Is eyeballing good enough? Yes! Does it annoy the piss out of me when a week later I notice the 5ish degree offset from eyeballing for some reason? Also yes.

Right. What really matters with a roof is that it keeps the rain out, but a roof that's out of square drives me insane. I got a few minor tisms and stuff not being square / plumb is definitely one of them.

If you use a scope level on your rifle and check it prior to every shot you will probably observe that your natural cant is not consistent.

...and (with practice) it does get better over time.

My UM Tikka dovetail level may (or may not) be off by a degree (or three) with regard to the action, but it's torqued down solid and dead nuts to the reticle. That's all I care about.

So you can do focused eyeballing of it and mount it to look as plumb to bore as you could visually discern but then days down the road you know its canted just from shouldering and looking through your optic after the fact? How does that work?
