Couple bubble levels and a torque screwdriver, use a Tipton gun butler to hold the gun while I get things level and tightened up.
I recently came across the Arisaka Optic Leveler, I have ordered one but have not got it yet. This video makes it look pretty useful

You don't need a boresighter for a bolt action rifle, just pull the bolt, sight down the barrel from the rear on a 100 yard target with your rifle propped on bags or a rest, then without moving the rifle look to see where your crosshairs are aimed and move in the direction that they are pointing, in other words if the crosshairs are aimed 12" low and 6" left, move the stadia, 48 clicks down and 24 clicks left (for scopes with 1/4" per click adjustmemt at 100 yards). This will get you on an 8.5"x11" paper at 100 and zero from there... I can usually get within 4" of the bull with this method. This is also a rough way to check your scope in the field if the rifle got bumped or jostled.
- I use a good gun vise that locks the rifle in tight.
- locktite the bases
- set the rings and mount the scope
- adjust scope for desired eye relief
- two bubble levels; one for the gun and one for the scope
- with the gun locked in level then level and tighten scope
- old Bushnell boresight tool
- first shot at 50 yds comes in close to center requiring scope adjustment
- move to 100 yds for 1/2" to 1" above bullseye.
When I get home I put the gun back in the vise and install the boresight and record the difference between original setting and final sight in setting so I know where to adjust for my next gun of this caliber.
protect the gun from the vise.
I use Goop under bases with blue loctite on screws. I mount rings on bases loose. Then i use a 36" wooden dowel in the rings. Torque down rings to dowel then torque rings to bases. Then check to make sure the long end of dowel is directly over the barrel. I have had to use millet adjustable rings or burris signature zee with offset inserts to bring dowel over barrel centerline. Also, for a used scope i return crosshairs to centre by counting turns from stop to stop. Was running out of clicks L-R this helped alot
I use the same wheeler kit that is mentioned previously. Has anyone else found that the levels aren’t accurate? If I place my levels on a level surface they will place the bubble in the centre, if turned one direction. If I flip them 180 degrees they will not centre the bubble. This means they aren’t accurate. I’ve just started shouldering the gun and adjusting as I feel necessary. Definitely use a torque wrench and blue loctite.
I settled on the Parabola Reticle-Tru and a good inch pounds torque driver. Makes scope mounting easy, quick and accurate.
Boresight thru the bore or using a collimator, just depending. Either works well.
To return a used scope to neutral is quite easy. Set the scope down on a mirror and look through it and you'll see two sets of crosshairs. While looking through the scope adjust it until both crosshairs become one. Now you're back where it began it's life.
Do you mean put the scope objective lens down on the mirror and look through the scope at the mirror?
That's quite the idea! I might have to try that with my next used scope.
