All we had were a set of 10x Binos with us. As silly as it sounds the gun firing made the person with the binos jump just enough to not see impact.
Have you run a 100 yard tall test with your scope to rule out a mechanical issue. Most of the issues of the type you describe that Ive seen have been scope related.

Before you actually start chasing things that may or may not be present, I would redo this scenario either with someone spotting who can stay on his glass, or find a more desired location. The spotter does not have to be directly behind you, behind the shooter is good yes, but he can be 25 yards behind and still accomplish what is needed. Sounds like things were compounded against hitting the rock, and no one was proactive enough to do anything about it. Lol, I think we have all been there.
What was used to range the rock? So was it indeed 650?
As for the load falling apart the farther you go, if it was actually grouping or hitting 4" targets at 400 yards, it would really have to be bad ammo to spread to over 3 feet.

Not trying to throw a wrench in but I have a Browning A-Bolt composite stalker (purchased new in 2006) that acts the exact same way. It will shoot 3/4 - 1 MOA, with factory ammo, out to 300-350 yards or so but I can't get any sort of grouping beyond 400 yards. At 400 yards the groups have opened up to 2 MOA or more. It too is a 300WSM that has a 23" 1-10 twist sporter barrel and the BOSS system. I've tried a new scope, new stock, and different ammo. Nothing changed, it still does not like to shoot beyond 400. I have not tried to reload for this particular rife. The factory ammo it likes best is 165gn Federal Fusions. I will also mention that hits up to 600 yards showed no indication of bullet instability. One thing I have noticed is that it seems to drift further right of the target the farther out I shoot. I thought it may be canting but that's not it.
I've stopped wasting time on it years ago and just use it knowing my max range with it is 300 yards. I never bought it as a long range rifle but for more of a light weight stalking rifle that won't see much action beyond 200 yards so I came to this decision pretty quickly. My plan is to re-barrel it at a later date, after it sees a few more rounds. I honestly do not understand what's going on with it. I have no problems shooting any of my other rifles out to 725 yards so I'm 100% confident it's not me.
I'm tagging in because I'm curious to see if anyone can help come up with an explanation to this because I'm at a loss.

Thank you, I think we may retry this weekend. Yes it was 650, well 647 to be exact on my Gunwerks br2500.
I'm going to try to attach a rock I shot at 410 yards below just before attempting 650.
That's around 3.5 inches, I should have shot another but I didn't.

He also said no one was able to witness impacts. My experience, if you have no clue what just happened, how or why would you believe something is wrong.

Repeat
That certainly sounds like this gun as well, In fact I had a different scope on it last year (trijicon accupoint) and bought the VX-5 because I couldn't get decent groups past 300 then.. tho the Leupold has got me a little further, it could be due to the grater magnification maybe?
Perhaps Browning has some quality control issues?
Were didn't see impact as it happened but were able to account for nearly every shot in the dirt around the target.

GW range finder most likely correct. Good units.
Regroup and retry. One other thing like an above poster mentioned, a guy needs to get a grip on what the rifle is actually capable of.

Could u give us your mv and what ballistic coefficient you're using?
Do you have a level on ur scope?
400 yds of drop is generally between 14" and 24" so not a big difference between cartridges but at 600 things can really separate themselves.
It might be easier to shoot at 450 and 500 checking ur drops along the way

Tell us what they were, high, low, either side, apparently you have an idea of what happened.
