Help from someone who has used a boresighter

[mchees1]

I had a problem with my Ruger No. 1 after mounting a scope and trying to get it sighted in. I bore sighted it on the target at 100 yds. and cranked the windage and elevation knobs on the scope like I always do, then noticed that I had to click full right to get it to look like it would get on paper. I never had that happen before, but I still cast some doubt on my procedure in that I might still be doing something wrong. I should not have second guessed myself. The bore sighting and first shots roughly agreed that something was wrong and that I needed full right on the scope to get somewhat near 0.

I am looking at getting the Bushnell Professional Bore Sighting tool with expandable arbors to use to try and help diagnose where the problem is, but not having used one, I am not sure that it will work how I would like. Maybe someone can help me.

I have read the .pdf instructions for it, and in seeing how they want you to align the bore sighter to the scope crosshairs, then locking the bore sighter tonthe stud, I am thinking that the bore sighter would simply align and center up with the crosshairs and not show any wwindage sighting errors, really only giving some ok elevation information.

It almost seems like to do what I want, you might have to have a way of leveling the grid in the bore sighter (by way of various means), then getting the rifle level at the same time, agreeing with the grid, THEN seeing what the error is on the scope, letting the crosshairs fall where they will.

Comments, help?

Thanks,

Danny

As many of the reply's have stated I suspect the rings and their alignment to the barrel. One of the best lapping kits is by Kokopelli (http://www.kokopelliproducts.com/acckit.htm). Not only does that system show when you have perfectly aligned rings, has a great lapping bar, it also has a method to see if the rings align with the barrel. One of the alignment bars has a hole in it that you insert a rod into. When you look from behind your rifle, you can clearly see where the rings are aiming. I have used this with great success when installing rings and bases. I can usually adjust the rings or base alignment a little when tightening them to the receiver to get them aligned with the barrel. Then I lap the rings and go. I use a little scope resin to make sure nothing will move and haven't had any issues with any of my scopes. A little expensive but worth every penny.

My no.1 is about 12" left with any scope set to optical center, I needed to use the Burris signature ring insert system to get the bore and scope in closer starting alignment. Now it is zeroing at 100 yards with only a couple clicks right.

I assume you put the scopes on optical center using V blocks or a mirror method. Halfway between mechanical limits rarely, if ever, puts the inner adjusted tube optics on a scope's optical axis; centerline between objective and eyepiece lenses.

Save yourself some money Danny. Just bore sight with the bolt removed, on a spot on a target at 25yrds. Fire one round dead center and then dial your cross hairs onto the bullet hole, while holding the rifle steady on the center of the bullseye you shot at.
Now you can move out to 100yrds and fire a round and you should be on line, but maybe high, then just dial down to where you want the poi, either i.e. one inch high or dead center. Usually you can be sighited in with about 4 rounds.
Just a thought and so easy to do.

I'd never go back to that method after having bought my boresighters.

100yds is a half moon on bottom of target to me bore sighting puts me in the middle.
Burris rings with inserts for misaligned scope screw holes.
Swapping the rings around Has sometimes helped..

Yeah, shoot at dot. keep gun still, Move scope to bullet hole, go back to dot.
That's what I do on sighters at matches.
I do believe all do.....

This is something I have had my eye on to buy.
