had something wired happen today would like some opions.
remington 710 with new nikon 6.5X20 44mm got it bore sighed and went to sight it in today at 100 yards took 46 turns on the elvation dial to just get on the papper and still 10 inches high at 100 yards using the winchester silver ballistic tips in 150 grain yet when shot a a target at 30 yards was right above the center oif the target an inch high. Can some one explian how the bullet hits 1 inch above center at 30 yards and ten inches above at 100 yards confused and concerned.

thanks

Vince

My goodness.....this creates a bit of a dilemma.

You say 1" high at 30 yards and 10" high at 100 yards.....interesting problem. After shooting the 30 yard target, then the 100 yard target, did you go back and shoot both ranges/targets again? If so, did you get the same results? If you didn't go back and reshoot and confirm you initial results you need to do so to rule out problems with the scope or its mounting.

I'm not familiar with this particular calibre so I'm not in a position to advise in that area, however on a general note....it could well be that there is a real problem with your rounds. From what you wrote I am assuming that they are handloads?? If so, I would very seriously consider (I'D DO IT) pulling a couple of bullets and check your load. Also, you didn't list your load data.....there are some extremely experienced and knowledgeable handloaders amongst us here and I feel certain that listing your load data will give them the opportunity to critique this part of the equation as well.

Additionally, I would be having a look at the rifle as well. Is it a new firearm? Have you had it for a while; if so has it always been a "good shooter"? Have you done anything to the rifle since it last produced accurate results? Did you boresight the rifle or was it done at a shop? Check the crown...has it been damaged. 30 yards isn't that far, but 100 yards is starting to get out there. A problem at the muzzle will only get worse the farther away the target is...like 1" off at 30 yds then 10" off at 100 yds.

The more info you can provide, the better the chance that someone will be able to pinpoint the cause of the problem.

Let us know how things are going mate.

Cheers, Vince

I have the rifle for a while just purchased the scope nikon 6.5X20 4mm had it mounted and bore sightred by gun store the ammo is retail winchester ballistic silver tips 150 gr went to new scope this year for two reasons last the gun was a wallmart purchase with a cheap scope and it would not hold zero spent the bucks on better scope also thought I try supposedly better ammo used to shoot remington core lokt in 175 gr.
a two day doe season comes in on firday so I need to get this corrected to answer your other question did I re shoot at `100 the answer is no but made no changes in elevastion on the scope at the gun shop the guy stated he needed to shim the scope cause he did not think I would have enough elevation adjust ments on the scope if he did not the scope has 1/8 inch increments this is very frustrating think I should try 175 gr with the new scope and get ridd of the winchester superme 150 gr stuff ?

thanks

I shoot the same load in my Savage 116, 7mm. mag. I don't think it is the loads your shooting, It must be the scope. I would take it back to the shop, they messed something up in the mounting process or the scope is defective. Or the gun shop is...Good luck What brand , mod. rifle is it?
How many shots did you shoot? What type of rest?

called th ewgun shop he stated that high at 30 yards would be way high at 100 I always though bore sighting should get you on the paper at 100 he said not nesscarly he suggested moving it doen the 10 inches 80 clicks not sure I have 80 clicks left in the scope

Like I said before the scope is more than likely your problem, loose, mounted incorrectly, etc. as for the types of loads your trying, your rifle will shoot some better than others but you still should get it to hit better than it is at that range. The heavier loads will hit lower, but not that much. You have to get the scope right first. Check to see if the scope/mounts are loose or even check your fore arm screw on your rifle for tightness. Don't over tighten your scope ring screws. Good Luck

When they set it up for you they should have shimmed it to get you close with the adjustments in the center, you might have to take it back.

Too bad you didn't live close to me, I'd be glad to help you out on my range..

the manufactuer of the scope told me to remove the shim to correct the issue I am goign to try ti and see what happens thanks for all your help will let you guys know how it turns out.

glockman55

Sounds like a good idea, I would put my adjustments back to center, Turn the adjustment knob all they way then count the turns the other way till it bottoms out then go half the turns to center, then start out at 25 yds until you get it to hit dead on then move back to 50 yd. which it should hit a little high, 1" or less then go back to 100. As you know each click is 1/8" adjustment at 100 yards.

As far as the .338 win mag, it's a hard to beat round. I have a Ruger M77 chamberes in .338 win mag. I live in Michigan, so I don't really have a lot of use for it, but I did take it out deer hunting on year....way overkill. I'm not familar with the 300 win mag, so I can't honestly give you my .02 on it. I have heard numerous good things about it though. Sorry I can't be of more help.
