 Can't get my 7mm-08 grouping at all

I've got a brand new Remington 700 stainless with a brand new Nikon Monarch BDC and I'm shooting 140 gr. Remington Core-Lokts. Groups are all over the place. I'll have 2 or 3 stack up right on top of each other then I'll get a few wild ones that go nowhere's near where the others were. I have never had an issue sighting in a rifle like I have this one. Usually I shoot 5 or 6 out of my 7MM Mag. just to "break it in" and I'm golden. I've put 3 boxes through this 08 and its all over the place.
Here are my questions:
1) Assuming its not me, what is the likelihood of the crosshairs floating in a brand new Nikon Monarch?
2) One of the bolts on the bottom of the rifle that holds the barrel/receiver to the stock was about 1/8 - 1/4 of a turn loose. Obviously I tightened it. Can such a slight "looseness" like that have any real affect on the gun's performance?
3) Could it be the ammo? I've shot Core-lokts my entire life and have never had any problems whatsoever. I realize, though, some guns don't like certain ammos and some people swear by some brands vs. others. Perhaps someone's had a better experience using another type of ammo?
Like I said I've never, ever had any issues getting a gun sighted in so I'm stumped. If anyone has any thoughts on the above 3 questions, or any other suggestions for that matter, I'd greatly appreciate it.

Merely suggestions:
I would shoot and retighten your screws on the scope mounts. Keep tightening after every shot until you don't think you can tighten them any more. If you haven't used it before, may want to consider getting some Lock Tight. I higjly doubt a great quality scope like the Monarch is the issue.
I do the following all the time and even my marine buddy was taught to do this. After your have made and adjustment on the dial, give a the gun/scope a swift whack. It's suppose to settle all the little gears in the scope.
Definitely try another box of stuff, like the cheap Winchester silver box. May want to try another weight too. I;ve always been told with the magnum cartridges, to use heavier grained bullets. When I had a 300 win mag, it shot the 180gr stuff significantly better than the 150 gr of the same exact kind. Don't know why, go figure.

that barrel has pressure on it. i would let it cool properly between shots. i would plan on floating the barrel sometime. yes loose screws can affect the accuracy. are you cleaning the barrel?

I'll have 2 or 3 stack up right on top of each other then I'll get a few wild ones that go nowhere's near where the others were. What is "nowhere near"? 1" off at 100yds? 0.5" off?
2) One of the bolts on the bottom of the rifle that holds the barrel/receiver to the stock was about 1/8 - 1/4 of a turn loose. Obviously I tightened it. Can such a slight "looseness" like that have any real affect on the gun's performance? Yes, get a torque wrench. Stock screws can even be tuned a bit to improve accuracy.

Likely, all but one Nikon Ive owned has found its way into the trash can for a similar reason. #2. Those screws have a torque value I wouldn't use the tighten it up till it feels good method. Having said that I doubt it would cause what you're experiencing. #3. Maybe, my rifle shoots corelokts the best out of all factory loaded ammo. Check / tighten the rings & bases. Sounds like the barrel is heating up causing a change in POI, let cool completely like 10~20 minutes and try again. The first shot out of a cold barrel is all that counts when hunting. My 7-08's bore absolutely hates being clean now, on the other hand when it was new accuracy would drop off after 20~24 rounds. Go figure. Try different ammo, if you have someone close with the same caliber try to trade some ammo before you buy it.

are you cleaning the barrel? Yes. I cleaned after every few shots the first time I took it out but not at the range the last time. I did, however, clean it when I got home. What is "nowhere near"? 1" off at 100yds? 0.5" off? 2", give or take. If, for instance, it shoots 2 times to the right the third shot is often times high. Or to the left. There does not seem to be a rhyme or reason to why it goes where it does.

Have you tried it since tightning the action screw? The times I have seen such it is most often something loose. The action bolt you tightened could very well be your issue.
The scope is not an impossibility but I would check all mounting screws and action screws first.
I have had good luck with Hornsdy custom, LM and Federal premium in my 7mm-08, when not using my handloads.

Not meaning to hijack the thread but curious about:
"#1. Likely, all but one Nikon Ive owned has found its way into the trash can for a similar reason."
With a lifetime warrenty why trashcan a acope? Return it for repair or replacement.

welocme to remington
I know you dont want to hear that but thats why me and my group of friend wont own another REM.
the ony real way to help is to handload, need to check the throat and where bullet touches lands, most 7-08's have short throats and factory loads might be jammed against lands.
it aint your scope, get that out of your head, loose action screws do affect accuracy.
I bet your bolt is hard to open after firing it.

I'd try some different ammo and bullet weights just to see what your rifle likes best.
Also, be keenly aware of your cheek weld to the stock. If you're not getting onto the stock the same each time and your eye is slightly off you'll get those occasional fliers. Also, make sure that you don't have any shadow to one side or the other. Could mean that your too close or too far from the scope which could cause the odd fliers.

Have you checked the parallax adjustment on your scope? If your parallax is off, the crosshairs will seem to move in relation to the target every time you shift your eyes. At 100 yards, this movement can be several inches. To check your adjustment, place your rifle in a bench rest or sand bags with the crosshairs on the bulls eye. Without touching the rifle, look through the scope and shift your eyes from left to right. If the cross hairs move in relation to the target, you need to adjust your parallax.

I would keep the bolt action open between shots to help cool the rifle. Also look into getting the barrel glass bedded or free floated. And yes, make sure everything is tight.

That barrel has pressure on it. I would plan on floating the barrel sometime. My father-n-law has the same rifle , it did the same thing as you are saying . I took it home floated it and now you can cover 3 shots with a quarter . And it has a cheep Simmons scope on it .

Take a dollar bill and see if you can slide it under the barrel all the way to the reciever.If it wont slide all the way then the barrel is touching the stock causing your problem.It could be your holding it a little different or putting more pressure on that one shot.
Not all those that wander are lost..

I had problems with a new Rem 700 synthetic stock 243. Rems answer to accuracy was 3-5" at 100 yds was accepable and 5-6 was not unheard of...
Traded it and got a Tikka in 243, have not looked back.
The Rem, hotter the barrel, larger the groups/pattern

Does the rifle have the cheaper version of the plastic stock on it? if so, this could very well be your problem. I've seen those plastic stocks give people fits.
If the barrel is touching the stock anywhere, it needs to be floated. Some will argue the merits of pressure points, but I've never seen a remington that shot better with a pressure point vs one that's free floated.
And if the scope is truly in question, try a known scope on the rifle. I know it's a pain to yank one off one rifle just to try it on another. But it could help find your problem.

Everything I've ever owned except one shot core-loks great. I've had 3 Nikons and two were great. With that said, try a different ammo, and pull another known good scope and put on it. A poster above said "Nikon in the trash", you damn right. I knew I had good optics and spent hundreds on ammo before I found the problem. For me, "Nikon in the trash". As far as the Core-Loks there great hunting ammo. The first I will try in any gun because of price. But if it does not shoot it does not shoot. Try something different. As far as the comment on Remington rifles, I hate them, but the only one I own (Model Seven) is an awsome piece of equipment all around.

I wasn't trashing Core-Loks, My 6mm and .243 love them. My 7mm-08 does not.

Not a fan of nikon anything, has the rifle been beaded? Action screws and all ring and base screws tight? All could contribute
