Bore Siter

[Falcon]

Need to mount up a couple of scopes. Looking for a simple to use inexpensive bore siter.

Thanks,

I have one of these.  It works well enough, sometimes I have to shim the rubber inserts with a piece of tape but I've used from .22 to .50 cal.  Gets you on paper, actually it gets you pretty closed to zero once you get the hang of it.

I just set rifle on some sand bags, remove bolt look down the bore at target and adjust scope to line up with what I'm seeing.  Thats close enough to get on paper at 50 yards and adjust from there.  Dead on at 35 yards should be close at 100.

For bolt actions, remove the bolt and look through the bore. Pretty easy and as inexpensive as you can get. Has always worked well for me.

Don't believe the myth that any bore sighter can adjust a scope well enough to hunt with. Their job is to adjust a scope well enough to put the first shot on paper. As noted you can do that without a bore sighter with bolt actions.

I have done 3 scopes this year by looking down the bore at a red dot drawn on a piece of paper at 25', then adjusted the scope match. Worked great.

I don't even bother with shooting at less than 100 yards anymore. I set up my 100 yard target, remove the bolt, put the rifle on sandbags, and adjust the crosshairs so they're lined up on the center of my target. But it's still not a bad idea to start at 25 or 50 yards. I used to but just don't do it anymore.

Bob...agreed.  just need to get it close on paper.  Good ammo isn't cheap, so the less shots the better

That's the 1st 3 shots from a .50 cal Knight Bighorn after mounting a scope and bore sighting with the laser.  100 yards off a bench & sandbags.

Never used a bore sighter because I've never needed one.  Suspect that they are better now than when they first came on the market.

Ditto to those who remove the bolt and look down the bore.  My first shot at 100 yards is usually within an inch of aiming point.  Here are a couple of details that make my method precise:

1.  Pick something as far away as possible to look at through the bore.  That lengthens the sight radius and makes a smaller angle of divergence.  My all time best was a big insulator on an electrical tower a mile or two away.  If possible I look for something at least a few hundred yards away.

2.  When looking through the bore, adjust the rifle on the sandbags to center the sighting point not only in the bore but so that the circles formed by the bore, the chamber etc. are concentric with the sighting point in the center of all.  Takes mere seconds of extra attention.

When I bought a used rifle with scope mounted, I first checked it by looking down the bore and comparing that with what I saw in the scope.  It looked to me like the bullet would hit 3 inches high and left at 100 yards and that's exactly what it turned out to be when I first shot it.

Thats a tight group right there

I've always just looked down the bore's and set the scope accordingly. I like to use a telephone pole cross remember or a TV antenna when we still had them, I like to try to get one at least 100+ yards or more out. The farther the better, we used a bore sighter on our 20mm Vlucans on the firing barrel, I always chose a pole cross member at 1,000 yards or more to zero the scope or night vision scope (Ground targets only) all aerial targets were radar or gyro aided.
