Re: Scope Canting
Before you install your level, you should double check your rifle & scope alignment. The quickest way to do this is to use a weighted plumb line on your target. Mark high & low on the string and then draw your perpendicular line on the target. I use a square for this.
Level your rifle in a gun rest/vise (preferable) or on bags, using your level set on the rail. Once this is done, install the scope in the rings and rotate it until the perpendicular cross hair lines up perfectly with the vertical line drawn on the target. Make sue rifle and scope are perfectly lined up and then tighten. Once this is done, use your perpendicular cross hair on your vertical line as a guide and then mount your level. This will get most, if not all of the cant removed from the rifle & scope without firing a shot.
You can double check your work by firing at the line using multiple dial ups as you go.
