Thread: Scope levels - do they work?

So you can judge well enough without one?
As the range increases being level would be more important?
I guess I find it boosts my confidence to have a quick look
A scope with a bubble level inside the sight picture would be the best. Do US optics make one of these?
On a different subject I see you tensioning your sling when firing prone. Do you find it helps stability?
Thanks for the video.
