OT.Bore sighter for rifles and muzzleloaders

[mnjoe]

Looking for ideas what is available to save me ammo and time with sighting in. Also looking for something to check scopes when coming back from kids. Thanks

Those laser bore sight tools are just a ball park thing and form there you have to fine tune the scope. A bore sight will get you into an 18 inch circle maybe a tad bit better but that is about it. I have used them many times and that is about all the better any did for me. Used one not long ago on a couple rifles I have. A friend owns one and he left it here fora few months so I played with it some. Cost him $50 and that was on sale

I took the bolt out of my rifle nd looked through the bore at a bottle cap at about 20 feet and that got me pretty close too. Just have to make sure not to bump the gun as you are doing it.

I have an old one we had in the gunshop. It's really no more accurate than securing the gun in a vise or stockvise and bore sighting through the barrel on a distant object then lining the scope or sights up on the object. A friend did that for over 50 years by aiming the rifle at his mother in laws attic window about a mile away. She got real mad when she found out about it. Women, go figure! Not like he was aiming a loaded gun at her house.

Anyways, like Old said, you still have to bench the gun to fine tune it. If you lend a gun out to a kid better figure they'll screw with the sights.

When I remounted the scope on my 10/22 I locked the bolt open and put a piece of white paper in the space where the bolt is when closed and aimed squarely at a mirror, a few feet away, adjusted the cross hairs onto the white dot of paper reflected through the bore.
When I went out and fired a few rounds it was right on.

I have a B.S.A. bore sighter kit and it will get the bullet on the paper at 25 yards. You cannot use it for any kind of accuracy though.

With a steady rest you can sight in a rifle with one shot. Put up something large enough you you you are sure your going to hit it and mark an aiming point. Fire a shot and mark the bullet hole with an X or a black dot so it can be easily seen through the scope. Bag the rifle so it doesn't move around and put the cross hairs on the bullet hole you marked. Without moving the rifle use the scope adjustments to move the cross hairs to the aiming point. Done except for a checking shot.

Well, I have a BSA as well, and they are a little more accurate than that. Have set up a number of guns up, and had them within a couple inches at 50 yards. Keep a record of each gun, when I'm satisfied with sighting-in, and that way, I can check them later, be sure they're still properly adjusted. Son has a screw-in-the-barrel laser unit. Most times, both methods seem to agree pretty closely. Don't work well on high mounted scopes like on a SKS, however.

Yep that is pretty much what I said and the longer the shot there after the more likely you are to miss. I have a rifle I will be sighting in this spring for 400-500 yards and it is good right now at 50 but out to 400 plus yards well not so good

Back in the old days, when I had time to tinker, I would rig up a good solid way to prop up my rifle on the outdoor picnic table or something. Then find a distant object, remove the bolt from the rifle (naturally only works on bolt actions) keep working with the rifle till you get some real distant object centered when you look down the bore. I have use the water tower 4 miles away, or a distant grain bin. Get it centered in the bore, best you can, then without moving the rifle, move the scope till the crosshairs are centered on the object. Takes some "tinkering" but it kinda gets you in the ballpark.

Forget the boresighters. Take you first shots at 25 yards. Adjust for center there. That will keep withing 4 inches of bullseye at 100 yards. Then adjust for 2 inches high. That will have you 2 inches high at 200 and 1/2 inch low at 300.

I've got the laserlyte system, that goes into the bore and fits 12 ga-50cal-.22LR. Works great. Once you use it once, and then actually get a gun sighted in, go back and see where it is on the paper using the laser. Should be there every time you check it. Works great for me, and I haven't missed yet.

To the guy who said it take 1 shot......your method only works, if the scope is mounted correctly. I just wanted to mention this, because if the bullet needs to be adjusted say 3" to the left, and no height adjustment....and the scope isn't mounted level, you will notice that if you move it the correct adjustment for 3" left, it has now went up or down too.

Mounting the scope, lapping the rings, leveling the scope to the barrel, and proper tightening of the rings is crucial when I begin the sighting in process.
