Sighting in a scoped bolt action rifle
I decided to post this string in the rifle section as it has to do with sighting in a scoped rifle, the images are to help illustrate what I'm talking about, if it needs moved to the pictures section please advise.
This is the method I use for sighting in a bolt action scoped rifle, fast easy with great results. I realize many may do this differently and perhaps have a simpler an better method of doing so. Please feel free to chime in with your methods for doing this. You'll need a windless day (I prefer bright and sunny no rain). You need sand bags or other suitable method of holding the rifle dead on the mark. You'll need an adjusting tool for the elevation and windage scope screws cross hair adjusters (usually a small blade screw driver). I use a standard printer paper 8 1/2" X 11" with a black quarter sized black bulls eye. Bore sighting, I generally do this at 25 yards, remove the bolt an place the rifle on sand bags for support. Looking down the rifle bore center the bore on a target as best you can. Now looking through the scope and without moving the rifle make scope elevation and windage adjustment to where the cross hairs are perfectly centered over the target. Bore sighting is complete at this point. At this point I move to 100 yards with the same target. Adjust a viable power scope to the least power you get a clear view (for me that's about a 3 setting on a 3 X 9 power scope) Next chamber a round and with the rifle sand bagged secured in place with the cross hairs perfectly over the bulls eye gently (without jerking or moving) squeeze off a round. Next looking through the scope center the cross hairs over the bulls eye dead center. Next with the rifle secured carefully without moving the rifle adjust the windage and elevation cross hairs dead center over the bullet hole. Next chamber a round and with the rifle sand bagged secured in place with the cross hairs perfectly over the bulls eye gently (without jerking or moving) squeeze off a round. Look through the scope for the location of the bullet strike, if it's not dead center repeat the procedure. I realize many members on this forum know full well how to sight in a scoped rifle, I only posted this for those that have never done this before or use a more complicated time consuming method. I also do something many may see as foolish, I use a rubber mallet to bang on the receiver to simulate recoil several times each side to verify no cross hair movement (jump). I test fire another round to verify accuracy was not compromised. Hope this is of help to someone? |

You are welcome Czubek, glad it's of interest, when I posted it I almost had second thoughts.

Gus, aren't you supposed to sight in on the bullseye and move the crosshairs to the bullet hole?

That said, I've owned semi-auto rifles with scopes, but never used a bore scope to aid sighting in. I've always used the 'old military way'. Target with grids, 3 rounds at a time, wander down to the target, triangulate holes, number them and adjust scope after every 3 rounds. |

Well done Gus, allmost the same as my method.
But, I won't make ANY corrective statements because your method is well done! |

Thanks for the refresher, I've used that method for most of my adult life!

Simple, easy, I like that.
Damn. I have seen guys burning expensive ammo, sighting at a hundred yards. New weapons, new too weapons. Hitting 10 feet off target. Finally could not watch the waste of ammo. Told him too bring the target into 25 yards and at least get on the paper and adjust. But I like that Gus.. Good tip, thank you.

Another thing I learned from my uncle is using sight radius calculations for adjusting iron sights.
Terms Amount of Error: Measure in inches the distance from the bullseye to your shot. Sight Radius: Distance in inches from the front sight to the rear sight. Distance to Target: The distance in inches from your shooting position to the target. If you are shooting low, you would lower the front sight, and conversely, if you were shooting high, then you would raise your front sight. Add or subtract the number of thousandths needed to the actual height of your sight and you will have the correct height of the modified sight. Example At 100 yards, your shot is 6" low and the distance between your front and rear sight is 19.5". 6 X 19.5 = 117 divided into 3600 (distance to target in inch's) = .0325 Since you are shooting low, you would need to lower your front sight by .032". |

I am glad to see I'm not the only one who hits his rifles with scopes on them to see if the cross hairs hold zero.
Good tutorial. |
