Re: Scope sighting. which is the best way to do it.
The following is just restating what has previously been written by several qualified members here. This is just what I do and why.
I use the bore alignment method as well if I can get my mug low enough for a good line of sight down the bore. If unable to bore align I use the walk back method, starting at 25 yards shoot a round make an adjustment shoot one more, then repeat moving back in 25 yard increments to 100 yard line if need be, and then move to my zero distance if different from 100 yards. As Todd stated this is a good opportunity break in a barrel if a new installation. I was given a laser cartridge bore sighting tool and it works great if you can get the time of day just right were you can see the dot and still see the target. Where I have really seen benefits from the laser cartridge is when demonstrating the difference in sight line and bore line at different distances with AR type systems. The studs used with bore sighting devices are not evil if used properly they can save you some ammo if you can't use bore alignment, walk back, or laser cartridge methods. As has been previously stated do not jam the stud into the barrel and be mindful of your crown. Other considerations when setting your scope up are to center your windage adjustments by bottoming it out one way then counting until you bottom out the other way then come back 1/2 that amount. If you have the hunting style base with course windage adjustment align your windage centered scope using these screws to align the scope with the bore, this will allow you maximum windage adjustment each way when shooting in the future. Quality rings and base make a huge difference in overall performance don't cheat yourself and the systems potential by going with cheap mounting solutions. Frank has an excellent article in the articles section covering mounting your scope and getting your rifle set up, well worth the time to read. Good luck with your set up and let us know how it turns out.
