Q:
Yesterday decided to shoot my Remington 7400 30-06 and make sure the scope was zeroed. I sighted it in last year at 100yards, i was shooting 2 inch groups. This year when i shot it, i cant get it to group at all. I can only think of 2 problems. #1 i have a bad scope #2 there is copper fouling in the barrel. I have checked scope mounts they are tight, and when i say i cant get it to group at all, i mean 1 shot will be 6in high, the next will be 8in low. what is my problem.

i have also used 2 different brands of ammo with the same result.
Problem #3...the shooter. I find that unless I've been practicing throughout the year, I tend to anticipate recoil and my groups aren't as tight as they should be.
Try this, have a buddy help you sight in your gun. Give them a box of ammo and an empty cartridge or a snap cap chambered for your gun. Have them stand behind you and load the gun with one or the other after each shot...but you can't look to see if he's loading a live round or the empty. If the problem is you, you'll find out real quick because you'll flinch horribly when the empty cartridge is loaded and the gun will just go "click." It's almost embarassing really...but that's what it takes to practice good shooting form. Don't forget to wear hearing protection and good luck!
It is hard to diagnose weapons problems withoutbeing there but one thing I have noticed here is whenpeople have problems they ask Do you think it could be copper fouling? If you think that could be a problem then use a copper solvent and clean the firearm really good. I use copper solvent every 100 - 150 rds or so. I am sure then that it will not get to be to much copper in the barrell.
Congratulations, I'm willing to bet if you did a thorough cleaning especially the gas system your accuracy will come back. I've found that gas guns are very cantankerous when the gas system is carbon up. If you reload, I suggest 3 powders that I do know are truly real performers, Winchester 748, IMR4895 and IMR4064.
If your Remington has the wooden stock, be sure and check "all" of the screws, making sure they are tight. A buddy had this problem earlier in the year.
i know its not me, my brother also has a remington 7400 30-06. i shot a 1 1/2 group at 100yards with it at the same time. ill break the gun down and clean it.
Sounds to me like the paralax in your scope might be broke. This happened to me a few years ago with a Simmons 44mag scope. It was never dropped either. I sent it to them, they fixed it and I put it on my .22 and bought a 3X9 Sightron for my 30-06 and haven't had any issues since. Learned a lesson. Cheap things aren't nice and nice things aren't cheap.
Also if you still have iron sights shoot a couple rounds at a target about 25 yard away. This should let you know if it's the gun or the scope.
This problem could
happen when you
use two different kinds of amunition in the rifle. Also check if your scope will move the crosshairs when you move your head. I had that problem.
I would say the scope. Give your gun a good cleaning and try it again but if that dosen't help the scope and/or mounts may need replacing.
I have a Leupold on my 270 and it hasen't budged in 100 shots. 1" groups at 100 yards consistantly.
I went though 3 scopes, all exhibiting the same issue. The first scope was on to mounts and I couldn't site it in. Went back and they said the scope was broken and replaced it under warranty. Used a Weaver rail now. Storing it in a foam padded case. Went out next year - couldn't site it in (but it was bore sighted like the first one). No matter how much adjustment, it wouldn't move (just like the first one of the same mode). Went back, they said that I should buy a better model. So I did. And this third scope has done the same thing. Bore sighted, then when to zero in - it won't adjust. Tried bore sighting again - cannot adjust. As soon as I shoot the 30-06 Remington 7400 - it breaks the insides of the scope. I am back to open sights, sending the scope back to factory fore replacement. No scope for this gun (thought about red dot, but not sure.)
