Can someone give me a brief step-by-step summary of the correct way to sight in my .375 H&H? Include intitial bore sighting, if you would, please.
Frankly, in the past, I have just flung enough lead at the target 'til I finally got it right. There must be a technique that you veterans use that reduce ammo waste and range time.
Doing a site search was not helpful.
Set up: M70, Leupold 1.75X6X32E in Leupold QR's. Plan to use Leupold bore sight (recommend another if you don't like it, please). Thanks in advance!

Corny as it sounds, I pull the bolt and set the rifle on bags and literally sight thru the bore until the 100 yd target is well centered in the bore. Then without letting the rifle move, look thru the scope and move the reticle into the target, This takes some back and forth but it is quick, easy and more accurate than my tasco bore sighter gizmo with different cailber spuds.

I would center the crosshairs up on the Leupold bore sighter. Then I fire my first shot at 100 yards. If it is not on paper I would go to 25 yards and shoot it there, getting it zeroed at 25.
Once I am on paper at 100 yards I will shoot one or 2 shots then adjust the scope and shoot 1 or 2 more. When I am where I want to be at 100 yards then I do the 3 to 5 round test. I will also usually do a 10 round test with the load I intend to hunt with just to see if the group gets larger as the bbl heats up. I do not do my "final" sight in on the bench. I will shoot prone off of my pack with a long range rifle, and also sitting. With my Elephant rifles I shoot them kneeling and sitting at 100, kneeling and standing at 50 and 25 yards.
In other words I do my final sight in from hunting positions.
Hope this helps.

Let me add that once you get the proper zero you can again "stick" the Leupold bore sighter on the bbl and mark where your crosshairs are. Then you can check your "zero" anytime you want with the bore sighter. If it is not in the same place...something is wrong. I carry my Leupold bore sighter on all my hunts.

On any of them bore sight it through the bore till the targets in the middle of the bore and the scope crosshairs are perfectly on target. You can do this out your living room window if you don't have close neighbors. Then I fire one shot at 25 yards. Set the rifle on a solid rest and line the crosshairs up on the target, then while being careful not to move the rifle, adjust the crosshairs till they're on the hole made by the first shot. It helps to remove the elevation and windage caps first. Fire one shot to verify that it's on, then shoot at 100 yards for group. I often just shoot 1 shot, then adjust the sights, but if you do this you have to have confidence that you can call the shot. If you use this method, you'll have it sighted in in three shots. I ran a gun store for several years shortly after college and often sighted in 100-150 rifles before deer season for customers, this is the method I used to get on target quickly and not waste a bunch of ammo. Try it, it works.

I usually bore sight my gun at 25 yards, then shoot and adjust the scope so that the reticle the moves towards the point of impact . Then move to 100 yards and do adjustments with shots at that distance.

There are bunches of different tools and techniques that all work. Here a few links that might help or confuse.

Tiggertate has it right.

I just sighted in a 300 Win Mag today with a Leupold VariX III 2.5-8x.

As Tiggertate said, get a solid rest, pull out the bolt and look down the bore. Center the target at 100 yards while looking down the bore. Adjust the crosshairs to the center of the target. With this method, I have always been on paper with the 1st shot. I usually shoot a 2nd shot to see how close it hits to the first. Then adjust the crosshairs accordingly. I have Leupold VariX III's on almost all of my scopes and it helps that the 1/4 minute click is usually right on. I have sighted in A LOT of rifles this way (both mine and friend's) and I am usually sighted in with 3 shots. Takes maybe 5 shots on a bad day.

Give it a try.

JetBlue,

The techniques described above will all get you sighted in.

I have also used a laser bore sighter in my backyard, I think the particular unit is set up for about 25 feet IIRC. It gets you on the paper too.

I like to do final sight-in from field positions too, as some rifles change their point of impact when moving from bench rest to field positions. I also like to check point of impact for the first shot from the barrel, and the point of impact for a barrel with a couple of shots through it. I hunt with usually one or two shots fired so the point of impact is consistent (it should be for at least 20 shots with a properly broken-in rifle barrel).

tiggertate,



Works for me! I have always bore sighted that way. In my opinion and experience it is AT LEAST as accurate as those "bore sighters" are.



On an AR or FAL I simply take the upper off the lower and pull the carrier/bolt assembly. Even works for doubles, if you are one of the scum bags that puts a scope on your double. Unfortunately doesn't work on BARs, M21, or any other rifle in which one cannot look through the receiver.



The 375 does not kick too bad, but make sure you have a good grip on it and it is pulled tightly into your shoulder before you touch it off.
