    Go back to 400 and attempt to repeat former sub zero results. If they are the same as prior results, then possibly its barrel harmonics and bullet design. I agree that a glitch in any one factor of rifle control will throw you off.

    Skipping ahead, so apologize if already covered.
    The picture of the 400 rock seems to have only 2 hits. So, maybe it's not really "MOA" at 400?
    Second thought, aim small-miss small. Paint a black 6" or less bullseye in the center of the big orange.

    The op said in post #14. Barrel my have been hot. 10 or so shots at 400 yards. Then 10 more at 650. A lot for a magnum.
    Barrel heat
    Barrel mirage
    Parralax
    Cant
    Frustration of not hitting target
    Crappie barrel
    Fouled barrel
    Ammo
    All of the above?
    Hope he goes back and narrows the field of options

    WOW.. so many helpful replies, I think im heading back out this evening for a rematch, lol.. To answer the question about cant, I haven't checked level, I had Cabela's install the scope so assumed they leveled it properly (they said they would) but I was shooting off a bipod and a rear bag..

    Parallax is something I paid attention to but will keep that in mind.. I plan to recheck my zero, then go back to confirm the 400 and maybe close the distance on the 650 yard target to 600 even and retry..

    One thing im thinking about is, we are talking about a rock laying on a bank here, its by no means perfectly vertical so would be easier to over shoot than if it were flat, so Im going to stand a smaller rock on top of it to try and get a vertical target..

    P.S, I realize this thread has gotten several pages long now, and some have missed where I said it so ill say it again, I DO know where I hit, I was able to see the dirt impacts once the shooting was over, I just couldn't see the impact through the scope as the bipods jump clean off the table and land a few inches away, lol

    Perhaps you said you had a spotter somewhere in here,...but, if not'.., take someone along to call the impacts for you I'm sure that would help, also take a good spotting scope as well.

    Last, your quote; "I had Cabela's install the scope so assumed they leveled it properly (they said they would)" Don't bet on it :)

    Put on a level. I check for level just before each shot.

    Hey Tommy,
    If you were able to hold a 4 inch group at 400... not that much changes at 650 that things would be outside 6 MOA. You have a good optic so work on “keeping your face in the gun”(Phillip Velayo, gunwerks)” which means see your impact thru your optic. With practice, proper recoil management and a decent brake you will even see bullet trace to impact! Other than your scope fixation coming loose, your rifleman mechanics would be the only other factor to cause this. The first time I shot out that far I sucked, but you can’t shoot better the second time if you don’t try a first! Good luck with your shooting and hunting!

    I agree, Cabela’s would mess scope installation up 10/10 times. Besides if you don’t have a level indicator for reference it’s a moot point anyway. Holding dead on and dialed for elevation rifle/scope can’t makes no difference when hitting a nearly 6 MOA target at 650. More likely his custom elevation turret is off or he dialed it incorrectly some how.

    Check your torque on your rail and rings, if it's a free floating barrel run a dollar bill between it and the stock make sure the stock isn't touching it.

    Put a decent piece of card board "no pun intended" as tall as you can find to shoot at. Zero at 100 at a bullseye close to the top. Go out to 200, 300, 400, 500, 600 and shoot at the bullseye WITHOUT ADJUSTING TURRETS FROM YOUR 100 YARD ZERO.
    Then you can actually see where your bullets actually hit and get an actual measurment on the drop.

    If all is shooting as should, draw 12x12 1 inch grid and shoot at the middle bullseye at 100 yards and run your turrets to see if there tracking at 1MOA and the back to zero. UP TO TOP, TO EACH CORNER AND BACK TO ZERO.

    1MOA @100 can still make a decent shot out to 500-600 yards. It's beyond that when the rifle and bullet show what they are made of.

    If it's not any of the above, I would definitely run a scope down the barrel. Last time it wasn't any of the above on a rifle I shot, it looked like gator skin down the rifling. You may be getting that carbon fiber barrel shortly.

    I have to agree that this is not a certainty . I have many friends through sniper schools that also took that for granted and a few had their builds set up at Cablela's. I have had to fix quite a few messed up setups. Additionally, as mentioned aside from Parallax the Anti-Cant bubble level is key. Setting up a distance verified drop table in ballistics makes a world of distance.

    Best of luck.

    Painting rocks to shoot at...enough said as far as I'm concerned.

    Cabela's set it up? No need to check on their work.

    To clarify im talking about the entire rifle/scope as it sits while you are on target firing. You can buy a cheap level from ebay that clamps onto either the scope tube or scope rail. Make sure as you fire that the level is .....level. A few degrees off level makes a big deal at 600-700-800+ yds. This is often confused with wind/mirage but compounds the issue.
