I got a quick question for you shooters. I haven't been on here for a while, since last summer. I was shooting my .243 and zeroing it in. I used a bore sight for the first 25 yards. I went to about 50 yards and shot high. I knew I was going to have to make the adjustment, but I can not get it down and centered to my target. I was wondering if my new bushnell scope may be more sensitive or somehow different than others. Anyway I am shooting high, so I adjust my scope crosshairs lower. I my be confusing myself, but should I be raising the cross hairs to where the bullet is hitting? I know I sound stupid, but I never had this problem with my .270, 30-06, or my other 2 rifles. I am just wondering if there is somethnig different about the velocity or something about the .243 rifle.
Thanks For Anyones Opinions
If you want the Point of Impact (POI) to be lower, you RAISE the crosshairs.
If you have a rock solid rest and can move the crosshairs to intersect the previous grouping without disturbing the rifle, that is an excellent way to get the scope and bore aligned.
You can remove the bolt (if a bolt action rifle), make the rifle as solid on a rest as possible, sight through the bore at the center of a target at 25 yds and carefully adjust the reticle until both the bore and the reticle are centered on the target. This should get you fairly close to the target center with your POI. Make any adjustments necessary until the POI is dead center with 3 shots. Then, move the target out to 100 yds. The first POI will probably be a couple to a few inches high, dead center. Make whatever elevation adjustment you desire for the following groups.

Thanks a lot for the quick reply. I am going to shoot it some more right now. Raise the cross hairs! Thanks, I was a little worried I was going crazy, or bought a defective scope hehehe. You know how us plum dumb KY boys are hehehe.
Thanks Again

wldct,
USUALLY the turrets of a scope will have and arrow and a word (example, top turret will have an arrow in the clock wise direction and the word "up".) These will show the direction to turn the turret in order to more the bullet impact in the direction indicated... So, in the above example, if bullets were impacting the target higher than desired, you turn the turret counter-clockwise.
Good luck

They can be mismarked, or not marked at all. I have one scope that is marked 'left-right' on both turrents. No telling who messed with it.
Shoot it, run 20 clicks in one direction (write down which direction), shoot it again. That will tell you what you need to do to zero it. Repeat with the windage adjustment.

Thanks MikeG! I will have to do that. I shot it all day after the last post. It still was not acting right. I almost took it off and threw it in the lake beside my house. I think I will buy a really nice scope for this gun. I like it the best out of my .270, 30-06, 30-30. Although, I haven't shot a .308 or .223, but which ever one I really like I am going to invest a lot of money into it. I saw a leapold for $379 and it is rated high. I really don't like the reticle in it though. What scopes do you guys recommend or really like?
Leupold, Burris, Weaver, Nikon, top line Bushnell.

Shoot one shot, Put your crosshairs on your point of aim, and move the turrets which ever direction they need to go to move the crosshairs to your bullet hole.

Ain't nothing unique about the .243.

A lot of the Bushnell Elite models have issues of running out of adjustment. I had one and have heard of many others who have issues like this. You may have to go with Burris Signature rings and the offset kit to get everything back in the middle. Not all actions are square and you will need to make up for that with the offset inserts for the Burris Signature Rings. If you can move your turrets and see the crosshairs move, then your scope is probably fine. This happens most on Remington 700 actions. Those other rings will solve your pfoblems.

Now that you mention it, that makes perfect sense. That is the problem with my shooting. I ran out of room to adjust my cross hairs. Thats why I keep shooting high, and can not raise my cross hairs anymore at all. Also you mentioned about watching the cross hairs move when you turn the adjustments; I just did this after reading your reply. I can not see them move one bit, as I turn the adjustment. They moved when I firdt bought the scope and bore sighted them. I got it perfect at about 25yds. Then no matter what adjustment I made it kept shooting high at my 70yrd target. I may or may not have broken it when I ran out of turns and accidently turned to hard on my last adjusment(turn). I am going to take a different scope off my .270 and see if this is the problem. Also when I bought the rifle it had a junky scope on it. So I replaced it with mine, but left the old mounts on it. I will go tommrow and purchase a good set of scope mounts.
I would like to think all of guys for the replies and suggestions. Everytime I get my guns out I think of this website for some reason. hehehehe.

Don't give up on the rascal until you run both adjustments back to the middle. Bore sight as best you can by what ever method you can and adjust by shimming the base. This will solve your up and down and I believe make your scope last longer. After the rough adjustment by shimming use the up and down adjustment to fine tune and different ammo adjustment only.

Yeah, don't give up on it yet. Be sure the rifle is in a good rest and you are looking at a far distance to see if the crosshairs move. If you are just trying to see them move in your house or at too close a range, you will have a hard time seeing them move.

Don't throw the scope in the lake, I will take it :rolleyes:
If the problem is really with the scope, you can send it to Bushnell's service center along with a description of the problem and $10, they will send you a new scope pronto.
If the scope is running out of adjustment, it is a mount or rifle problem. Any scopes best performance is with the crosshairs near zero. A Bushnell new in the box has an excellent set of instructions for installing the scope and the need to shim the mounts if they are not aligned. You should not use the crosshairs to correct a mount problem on any rifle. Crosshair adjustments are used to correct ammo POI vs. POA. Shims correct mount alignment issues. If the scope mount isn't adjustable, wafer thin sheets of brass (various thickness) are cut and used under the mounts or between the rings and scope tube. I bought a envelop of these shims about 25 years ago, a nice supply for a few coins, and they last forever and are reusable if you remove the scope or receiver sight.

Thats Funny! When I was trying to zero my .270, I used pieces of a cardboard box to see if helped my adjustment, and it did. My father had it set up great, but had an older scope on it. I bought a new one to put on it and thats when I had to experement with adjustments and made temporary shims. The base and rings I had to get on look a litte differently on it than my other rifles. If you look at close you can see that the front mount is lower than the back mount. It shoots awsome. I just thought that was ironic about you making shims, and I did the same thing on my .270.

I used to do that and put scars on my scopes doing it. Now I just use Burris Signature rings and get the offset inserts. If you have a good scope, its best to do whatever you can to not scratch it. You might want to sell or trade it one day, and one without scratches will bring you more money. Something to think about.

I would go with plastic inside the rings also. My shims are under the mount.
Chief - I'm with you! Just the cheep side of my nature! :D
