Bore Sighting Question

I just put a new scope, rings and base on my Remington 700 .270. For those of you that boresight your own rifles, how do you do it?

Should I buy a laser boresighter, or can I just look down the barrel and adjust the scope? Also, at what range(s) do you generally bore sight?

I have sighted in several scopes before. But each time I just started at a close range and worked my way out. Wanting to save a few steps and some ammo this time.

Any advice and details would be much appreciated. Thanks!

W/a rock steady rest, take the bolt out, look thru the bbl & match the cross hairs to the target @ 25yds.
Fire one shot to make sure you're close, adjust as needed.
Move to 100yds. & fire one shot.
W/out moving the gun, move the cross hairs to that bullet hole. Should be done but need confirmation shot.
Fire one more to confirm/fine tune.

Good luck!

LFD2037 nailed it. I have an arbor and a laser bore sighter because I used to mount several scopes a week. If only done occasionally then the method above works great.

This. With a modification, I mount and bore sight at home. I have sighted at objects out to 50 or so yards through the bore. (like a post and top rail on a chain link fence) then one shot, move the cross hair to the shot.....the farther you can bore sight the closer to zero you'll be.

since I am now stuck in the big city for a while, I have been banished to shooting with the masses at public gun ranges. I just can't describe how many times I've seen folks shoot BOXES of ammo trying to hit a target and scratching their head after they paid to have their new scope "boresighted" at the local gun store. If I get an opportunity to help, this is the method I use as well. I go straight to the 100 yard line with a 6" black round target on a big piece of paper. Rarely takes me more than 3 shots and 5 minutes to zero a rifle scope (with good equipment.)

I do exactly what LFD said, but I use a distance of about 100-200 yards out. 25 yards is way too close, IMO. If you sight in that close, you will be off at 100, which takes more rounds. I want to bore sight and zero in as few shots as possible. If you get the center of your sight picture through the bore to the center of the cross hairs at 100-200 yards, you will be within a few inches of zero. I'm often about 2-3 inches off. If I'm at home, I'll lay prone with the rifle supported on a bipod, and look through the glass door or window, and use the neighbors chimney or roof line. If at the range, I'll use the 100 or 200 yard target to bore sight through.

Also, when looking through the rifles bore and dialing in the scope, the adjustments are backwards. To move left, you dial right. To move up, you dial down. I do this method with almost every rifle I shoot, so several times a week.

I can't see 100yds. w/out magnification is why I start @ 25yds. If you can see 100-200yds. then by all means, start there. I wish I could! Damn astigmatism is a PITA when trying to be half-[censored] precise.

LOL!!! True dat!

Looking through the reduced area of the rifle bore actually helps reduce the detrimental effect of astigmatism, just like looking through a peep-sight does. Even with my 70+ year old eyes, I can get on paper bore sighting at 100yds. With an AR type rifle, I take the upper off and bore sight that way. With a lever-action I use the "shoot at close range first" method and make sure I have a BIG target. If you are not on paper with your first shot, you can really waste a lot of expensive ammo shooting who knows where....

Unfortunately I can't see well enough so I use the Pursuit bore sighting kit (arbors from .17 to .50 and shotgun). Works fine.

Works every time. I personally try and leave that 25yd shot about 2" low, then move to 100. Not a deal breaker though. Like others, I cannot see the target well enough through the barrel at 100 yds, much less 200.

Yep, wear bi-focals. See close okay far away is a bummer. Have to use a scope can't focus open sights to distance object, have to bob head up and down.
At home set up 25 yard target bore sight then two the range.

I also do 25 yards. I can't see past that. I just setup a 30-06 this way and only had to make one windage adjustment.

I've gotten into the habit of bitching about having trouble seeing close up. I guess I've really got no reason to bellyache. Not much, anyway.

You fellas who have trouble with iron sights, I can sympathize with you...but if you've never looked through aperture sights, you really oughta give it a try. The smaller the aperture, the better.

I bore sight on a neighbor's porch light about 100 yards away. I will usually fire at least one round at 50, though, just to be sure I'll be on paper at 100. I do have one rifle that just does not tell you where it's going to hit by boresighting. I think the receiver's D&Ted a little off center. Shoots good, though---once it's zeroed.

Yup

I perform this task the same way Chad does.

ARs are a bit harder because you can’t remove the bolt. Sometimes I find it helpful to use a laser to get the left/right alligned.

Huh?

Can’t see through barrel with bolt out like you can on a bolt action

You can if you separate the upper from the lower. I have a cleaning rod guide that I can see through and it will hold the upper/lower apart, but I've not gone to the trouble to figure out how to take advantage of that for bore sighting. It's easy enough with upper and lower separated.

I think an AR is the easiest. Just take off the lower and take the BCG out. Done!

AR is easy but not as easy as just pulling the bolt on a boltaction to me. Lever actions are the most pain to bore sight to me.

I usually bore sight at 50 yards and shoot to verify before going longer. Msny cartridges that will put you very close at 100 yards.

That's odd you say that, since I've done it about a hundred times.

Well you are the god of shooting as you like to spout off

It can be more difficult on ars with the just the upper, as it's harder to brace. There are things you can do to help but it can be difficult for people doing it for the first time.

Now you went to far.

It's not my fault when idiots get on here and give what they think is good advice. And other people are going to believe that is good advice. I can't abide that. You just gave bad advice based on your personal lack of brain power to do something, and was called out on it. My 9 year old daughter has learned to accept being called out. Evidently you missed the lesson at some point in life.

Pull the back pin, split the upper from the lower, pull bolt and changing handle. Upper on a bipod or laying across a pack and bore sight down the bore like any other rifle.

"Can't see through the barrel". Your quote, and it is completely wrong.

Said it poorly I will admit that. I restated it

It's not my fault when egotistical people say the only way to do it is their way. There are many paths depending on circumstances and equipment. The people I know care about listening to other people and accepting if they can learn another way of doing things and being humble about it. But apparently you missed that lesson

I did not miss that lesson. But I have had to bore sight the old school way after a guy has his bore sighted with lasers, muzzle gizmos and the like. Because the rifle and scope wouldn't even punch a hole on 2' x 2' paper at 100 yards.

But you stated something that is simply not true. And more people that me have said so.

Easiest rifles to bore sight through barrel are the Falling block rifles like the Ruger @1 or Dakota 10 both of which just require opening the action

Next would be bolt actions where you only have to remove the bolt to see through the bore

A little more complicated are the AR family. Separate the upp and lower. Remove charging handle and BCG and good to go. Bags that clamp onto the forearm make holding the upper solid help in this, Uncle Buds Bull bag works very well for this as well as the other actions when bore sighting from a bench

Lever actions can be done but is a little more work in disassembly but on my Marlins I have bore sighted this way.

I have several of the "bore sighter" commercial rigs and find them to be the most useful when changing scopes. Clamp the rifle down in a bench vise, attach the bore sighter and record where the sighted in acope is on the grid. Replace scope and set it to the recorded point on the grid, you will be very close.

So as I said earlier I did not post clearly. Not sure what happened to the rest of my post


Since you can’t remove the bcg and still have the stock they CAN be a bit more difficult. As stated remove the upper and bcc and you can do it that way. If you don’t have a good support it CAN be a bit more difficult. As note I have seen someone kicked off a public range doing this Because he was not on paper with 2-3 shots. One thing I SOMETIMES do is to bore sight with a laser just the left/right poi so I only have to focus on elevation which in my experience is a bit easier.

If you haven’t done looking though the barrel it can be difficult depending on eyesight, bags/support, etc.


I am well aware bolt can be removed, I was talking in context of a complete rifle (which is easier to stabilize)


So because you had a bad experience with one guy doesn’t mean it’s a bad method. Depending on how he used a laser Ie if he tried so many inches at so much distances, those calculations are depending on functions such as scope height which as you know on an ar tend to be relatively higher than a bolt which skew those old “rule of thumbs”. Kinda of like an ar zeroed at 50yards does have the same zero at 200, etc

You take one example without knowing why it happened it say lasers are bad. I know man people that have had good results with a laser.

Is "you", me?

If that's the case it is not that I've seen "one guy" have had results from a laser, it has been multiples of 10. Evidently you don't know how many rifles I'm around throughout a year.

It’s not about the technique. It’s the application. You can have good and bad application of both. People need to find what works for them.

But you have been though sooooo many rifles that you know evvvvvverhthing about shooting. I bet some people have even used lasers before they went to ur range.

Whatever.

You can have the last word. No point in me repeating myself. I already made the point, and you helped. Yes people have used lasers before coming to my place, and I had to fix what the laser did. Clearly that went right over your head.

I see what you did there say you can have the last word then make one more Jab... classy


Application trumps technique. You can get on paper with both they get to the same goal. My point is If you can not do it one way try the other. I have used both and both have worked. I understand that you have had to fix people who have tried laser technique. That’s application error. As I stated I have had to help people that failed by using the barrel technique. Those are application failures not technique. I am just proposing that using a laser can get you on paper and some people can use that as an alternative if they desire

Keep writing. But this^^ is still spreading false information. Also known as a lie, unless you're a politician.

Already agreed twice . Nice straw man to tie me to an argument I am not making in order to try prove me wrong

Think lie is a bit strong. Lie implies intent to deceive imo. Wrong, untrue, not correct, would all be a bit more appropriate

So you're feelings are hurt because I called a lie, a lie? Men don't do that.

Want to keep going in circles after your original lie?

I even linked to where said it was wrong

I admitted it...how are my feelings hurt? I was giving you better word choice

Because you need more explaniations

The definition of a lie

used with reference to a situation involving deception or founded on a mistaken impression

Here there was no intent of deception wereas a falsehood is a fact that was not correct. In this regard I said there was no bcg, but what I meant to say was that you can not say through the barrel with the lower attached even if you remove the bcg.

Regret lying, getting called out, then turning into a rude smart alec now?

locking, hope the OP has his answer.
