No Bore Sighting? How To Zero My Scope?

Blackbeard · #1 12-20-2010, 12:57 AM

Howdy!

I took my 15-22 to Academy Sports the other day, to get a Free Bore Sighting, since I bought my scope there.

I had purchased my scope and rings while they had a sale on, and I was waiting for my 15-22 to arrive at my FFL Dealer. I installed the riser, rings and scope, then off to Academy Sports I went.

The gent at the gun desk slid the Bore Scope into my barrel, and then immediately said, "I can't do it. The barrel is a lot lower than the scope." He explained that because the barrel was much lower than the scope, it was impossible to do. True, or did he not know what he was talking about?

He mentioned that I'll have to Zero it in at the range, and that it was a good thing that 22 ammo was cheap.

Anyone else deal with this issue, when sighting a scope on the 15-22?

Yes, I looked up Bore Sighting and Zeroing a Scope on SEARCH, but didn't find the answer I hoped I would.

Thanks for any inputs. Can't wait until Christmas, when I can finally shoot this thing!

Cheers!

yep...he told you right...as to sighting in at the range...it only takes a few minutes...no big deal at all...

It's true. The bore sight it too short to use on the AR. Just start close enough to get on paper. Start at ten yards or so and set the sights about 2 1/2 inches low. Then just keep moving back about 10 yards at a time and it should be fine.

Ooops, deleted post, I thought you were at a range to get it bore sighted. My bad. At a range with the right bore sight, you'd have been fine.

try this method, YouTube - Sight In Your Rifle in Two Shots - NSSF Shooting Sportscast

but, obviously it isn't as accurate so it is going to take more than just "a few". I'd shoot 3 shot groups then adjust. three more, then adjust. repeat and repeat til perfect.

Crack open your AR and take the bolt out. Lay the receiver on a bag or two and peek down the bore and adjust the scope to what you see. You should be able to look through the scope and back to the bore a few times and tune it in pretty close. I have done a half dozen this way and it usually take me under 5 rounds to dial the rifle in perfectly. Good shooting.

Thanks folks!

We're heading to the Range Thursday, to get some time in before all of the "Kids with new toys..." flock to the range after Christmas.

While I can't shoot my Christmas Present just yet..., I will take your recommendations, and re-sight my wife's Marlin 795 Simmons 3-9x40 Scope. Last couple of times we were at the Range, it was still a bit off, even after some adjustments. This time, we'll use a couple of sandbags to hold it steady, rather than rely on her bipod and our shoulders to zero it in.

But..... on January 3rd..... when the kiddies head back to school..... I'm gonna sight in my 15-22, and empty a box of Winchester 555 down range!

Lotsa good info on here! Thanks again all!

Cheers!

+1

I have used this same technique many times with bolt action rifles and I'm alway on the paper at 50 with the first shot.

If the guy was using a laser bore sighter what he told you was only partially true. If he was using an mechanical bore sighter he was telling the truth. When the scope is high above the bore its hard to zero the elevation exactly but it doesn't matter for windage. What he should have done (if it was a laser bore sighter) is do the best he could. You would have been very close for windage and a few inches high or low a for elevation depending upon what distance you are going to zero the rifle for at the range. Even if the scope was very close to the bore and the other type was used you still need to do some fine tuning depending upon the actual range you want to zero the rifle at. BTW +1 on what Smith357 said. That will get you close.

all you need to do is go to the range.

step 1.. lay rifle in sand bags or vise and fire one shot at 25 to 50yds on a large paper with a very small dot

step 2.. make sure your cross hairs are still on the little black dot.

step 3.. while making very sure you do not move the rifle use the scope adjustments to move the crosshairs/red dot from the small dot to the bullet hole...

step 4.. fire a 5 shot group at the small dot on the paper

step 5.. make any fine adjustments that are needed..

this process should get you very close to zeroed the first time
