What is your best method for leveling a scope reticle and mounting a scope level? I want to make sure my scopes are level and not canted. I've mounted quite a few scopes and never have came up with a good way to level the rifle.
I assume one must level the rifle.
then sight the scope on a true vertical string.
then mount the scope level on the level rifle and plum reticle.
I'd appreciate any pointers....

I use a gadget called the EXD Engineering Vertical Reticle Instrument and a plumb-bob. Once the vertical reticle is correct just make the scope level bubble match the "instrument" bubble. Works great.
$46 from Brownells. Here's a link:
The photo kind of misses the whole point as they have the side with the spirit level turned away so you can't see it.
Be aware that once your buddies learn you have one of these it tends to get "borrowed" a lot.

Level it to the bubble, and adjust the crosshairs to the tool....

No tool will do it perfectly as far as I am concerned. The only way to be sure is to shoot. Start by making a perfectly perpendicular line at 100 yards and shoot at the bottom of it. Now move your scope up 20 moa or so and shoot again. It should cut the same line. Finally shoot at the actual ranges close and far to confirm the results. This is the only reliable way to do it as far as I am aware.

From the instructions:
"The device is fabricated in two aluminum parts; the smaller part has a bubble level mounted within to insure the device, and ultimately the rifle / scope combination, is level. By placing the longer portions v-block end onto the barrel, the device is then placed in front of the scope and the v-block of the smaller part is placed on the loosely mounted scope.
"Slowly tilt the firearm slightly from side to side until the bubble is centered exactly between the calibration marks of the level vial. Then view the vertical reference line you have chosen through the scope. If the vertical crosshair of the reticle is not perfectly parallel with the vertical reference line the scope body must be rotated slightly and these steps repeated again."
As I said, I use a plumb-bob at 100 yards as my "vertical reference". The only time I've had a problem with it was with a Leupold 40X Competition scope. You actually look through both the scope and the vertical slot in the "gadget". With the high magnification of the 40X and most of the objective lens blocked by the tool, the string I used on the plumb-bob was difficult to see.
