try to clean the bore and make sure there is no build up in the rifling, and if that dosen’t help you might want to check into the scope. Some scopes can’t take the recoil. Just remember that just because a scope looks good, dosen’t mean it is. There are a few good scopes out there that are resonably priced. Talk to the dealer where you purchased it and they will help you find the one that fits you. Leupold is a good one.
Make sure all of the screws on your rings are very tight and there is no movement between the rifle and the scope. Make sure you replace the caps on the adjustment knobs and see that there is no play in the knobs, they should not move too easily. Screws can easy be shaken loose from recoil after a few shots if they are not tight.
before I sight in a scope, I like to shoot a few rounds then run a few patches through the barrel, and repeat a few times to ensure everything is consistent.
After you’ve checked the optic and the rifle the last variable is you. Make sure you shoot from the same position and strive for consistancy.
If the problem persists, I would recommend buying a quality scope. Leupold, Nikon, Burris, Bushnell are a few good brands.
Make sure that your rings have not come loose from the recoil. Also it could be because your barrel heats up after that many shots and will not give accurate results. The other step to take is just clean your bore with solvent and brush. that should take care of all of the problems. Also check to see if your scope is not touching the barrel, if it is, it is mounted too low and that is your problem
Your $15 dollar scope can’t stand up to the recoil of the 30-06. Possibly loose mounts or rings but get a real scope before you waste any more ammo.
Leupold and Burris are made in the United States of America just like your Remington SPS.
With a super cheap scope you also have garbage mounts and rings.
Yes, good equipment is a little expensive.
Do you want to hit what you shoot at?
That sounds about right for a barrel that was cold and then warmed as you shot the groups. My Win 70 does it 6″ right and then 1″ separation per round as it gets warmer it drops the 1″.
First things first, you have to clean your rifle. Now, that this is done, you have to make sure that your scope is tight. Done? Good, now when you start grouping, use 3 rounds to make sure that your not jerking the trigger, and stop breathing as you are about to pull the trigger. When you aim, always have the same picture in your scope. Cross hairs level and straight up and down. After you make 3 good grouped shots, then adjust your sights and fire 3 more for grouping. This will give you an idea of where your aiming, keep it up until your on target. Once your on target, put the gun away for a day and come back the next day to see if your still firing the same way.
Cheap scopes are sometimes very good (especially in the last 10 years). I’m not familiar with NC Star though.
Cheap mounts and rings are not good though !
I’d take things one step at a time
Buy a good weaver style or standard style mounts/rings and see what happens. If that doesn’t work for you, buy another scope too.
You don’t have to spend a whole lot of money on a scope. A busnell 3200 to your door should be less than 200 and it will last forever.
At 100 yards, deviations of that magnitude do NOT come from warm barrels or dirty bores.
The most likely culprit is that the scope mounts are being rattled loose by the recoil. Try tightening everything, and putting LockTite on the threads.
The next most likely culprit is the scope itself. Do a quick Google search for NC Star scopes, and look at the hits on shooting forums. No one has anything positive to say about them. The internal elements are probably being shaken out of alignment.
You are the next possibility. Since you shot on different days to get the different results, it’s possible that you aren’t being consistent.
And the least likely possibility is that your gun is broken. But a new Remington 700. . . it seems unlikely.
Start with the top and work your way down. If the rings or mounts are loose, that’s your problem. If they’re good and tight, then take that scope off. The SPS doesn’t have iron sights, so either stick another scope on it, or shoot without, just aim down the barrel. If it groups will with that scope gone, then it’s your problem.
I’m betting it’s both the scope and mounts. There’s just no such thing as a good, cheap scope for a high power rifle. Spend a reasonable mount of money for some quality glass and mounts.
