Bore sighting

I never realized how off bore sighting could be. I have always sighted my rifles in and went through much ammunition to zero (we have a stable platform but no vice). I decided to get them bore sighted by our local gun shop and made the mistake of not realizing that they could be off. Went hunting with them and couldn't hit a thing. My 30.06 was off 32 clicks up and 18 left @75 yards, and My father's 270 WBY Mag was about half of both of those (they wern't off that much to start off with). I wish I had found this forum before I wasted a day. Thanks for being here I will be checking this forum any time I try anything new from now on.

The bore sighting is only to get you on the paper the rest is up to the shooter to zero in also recomend to use the same bullit you will be using for your hunting and if you change the wt .. or brand take a trip to the range Thumbs up

We try to stay brand and load specific with our ammo, easy to do with the WBY mag but expensive. Not so hard with the .06 either. The bore sighter was not a laser and the .06 was off paper so I think I will stick with sighting through the barrel to get us on paper. Thanks for the advice, and good hunting Thumbs up

I never even gave any thought to the fact that someone would actually think that bore sighting was an accurate zeroing. eye roll

..I once had a hunter come by my camp one time while i was having a cup of tea we got talking and he asked me if i would look at his rifle , he explained he had just bought it and the scope was not to good as when he looked through it everything was a blur I discovered he didn't know that it had to be focused ??? nor did he know how .then I asked if he didn't have dificulty sighting it in , he explained that he hadn't fired it yet !doh ! there are all kinds out there never ever assume that all of the guy's out there in orange know what there doing ! or know what you know

I've bore-sighted scopes since the early '70s

Best way in the world to "rough one in" I've had several rifles that I can remember, where they were dead on the money, and required no fine-tuning. I did own a Remington 700adl (243) once that you could not bore-sight. If you went by the bore, you would swear that the gun would shoot to the right. I bought that gun used, and it was a tack-driver. But it was as if the barrel was bent. Looks were very deceiving.

I'm having trouble sighting in my rifle. It is boresighted(supposely cabelas did it when they mounted my scope). I started off at 25 yards, and my 3 shots were up and to the left about equal distance. I tried adjusting the scope(I'm not sure which way to turn it) and it just made it worse. Ugh!

What kind of scope is it? Does it have instructions? Don't worry, most shooters don't read them until there is a problem. Anyway, there should be arrows indicating which direction is up and which is right.

You can do what's called a poor man's bore sight if it's a bolt action. Set up at 25 yards (50 will do if that is as close as you can get). Remove the bolt from the action. Look down the bore from the chamber end and line the bore up with the target. Now gently (don't move the rifle) look through the scope. Repeat a few times until you get the hang of doing it without moving the rifle. Now, turn the elevation knob in the direction needed to bring the reticle to the center elevation of the target (you will see the reticle move). Do the same with the windage knob.

Put the bolt back in and chamber a round without moving the rifle too much. You should at least be on paper at 25 yards. Shoot the rifle a couple times and adjust the scope until the windage is centered and the elevation is at least close. Now take it to 50 yards and shoot and do the same thing. Once set at 50 yards take it to 100 yards and do it again. From there you can get zeroed at any distance with ease.

I use a Burris FullField II. The elevation knob says which way is up, but the windage one doesn't say which way is right/left. At 25 yards, I was shooting about an inch up and an inch left of the bullseye. I would click the knob a few times down, and it didn't seem to make any difference. I think I will look into buying a rest for my rifle so I can have it (95%) steady and in the same spot and go shoot 40-50 rounds until it is dead on and I figure out how to use the scope better.

I think the Fullfield II uses 1/4moa clicks. At 25 yards you won't notice as much movment so you probably need to put more clicks in. 1moa at 25 yards equals 1/4 inch.

As for the windage, I believe the arrow indicates right movement. If it doesn't have any indication at all you should contact Burris and ask why.

5 Tips for Sighting in Your Rifle (featured article)

I have been visual bore-sighting for over 30 years, and it's a good way to "rough-in" your scope. I don't trust collumators. And, I thought of the cartridge lazer-light device before it ever hit the pages of Cabella's. Never followed through with the idea, though. Here's another idea that I thought of about 20 years ago, and to my knowlege, it's still not one on the market. I TRIED DESPERATELY to contact the folks at Knight black-powder guns. NONE OF THOSE PEOPLE WOULD RETURN A PHONE CALL. It's a simple idea for an in-line or breech-load gun. It's simply a plastic(or other material) cap to fit over the end of the barrel, or muzzle, of any designated make, model, or style gun. This cap will have a set of cross-hairs, or cross-wires, to look through(while bore-sighting). When you remove your breech plug,or bolt, and you have a good through-the-bore view, you simply line up your scope recticle with the cap-contained cross-hairs on a distant target. This should be done in a vice, or solid rest. Then, take the cap off and shoot to fine-tune. Just think.. If you could carry one of these in your pocket, and you dropped, or bumped your gun, and had some doubt as to whether you were "still on the money", you could pull the bolt or plug out, cap the barrel and look through to re-check, without firing a shot. And it would be a cheap item to manufacture......Just remember me if you can sell the idea...
