I would not return the rifle with optic, can't believe they would want anything but just the rifle.

Max COAL is listed to ensure that it will fit pretty much any rifle out in the wild, without problems. If you have one specific rifle, you can safely ignore that spec, and load to whatever length you need. Your new limitations will come down to how long a round will fit your magazine (assuming you use one), and how long you can load before you can't safely extract an intact, unfired cartridge after chambering (i.e. for hunting, you don't want to jam the bullet into the rifling.)
What's your setup at the range? I'd suggest a setup that allows you to get on target and be able to release the rifle and have it stay that way: good front bag, rest, or bipod, and a somewhat formable rear bag to support the butt of the stock. Removes most reaction to the extra recoil as you're not using muscle to hold the rifle on target.
I second the suggestion to swap scopes between rifles. Easier than shipping it back and waiting for them to tell you nothing's wrong with it.
This is interesting Max COAL I’ve seen is 2.800. I have put one in dry and tested out to 2.825 and saw no rifling marks. However a factory 129 Hornady is 2.690
I do feel the most comfortable and quiet off bags or bi pod and rear bag.
It’s already at Savage and they were fine with scope on. Wish I had swapped out before .
Thanks for your help!
In my experience, seating depth changes within reason has never caused the extreme spread the OP stated. His description of extreme group spread has the classic sound of a bedding or scope issue. I would bet of the bedding issue.
I did have one rifle in my many years of shooting that had a factory defective barrel, a Rem 700, 22 250 that was grouping over 2" at a 100 yards. My smith determined that it was a "cross cut" rifling. It took some doing but Remington final admitted the mfg. defect and sent me a new rifle via my smith.
More information is also needed. Do the flyers occur at random or after a set number of shots? Are you shooting out of a hot barrel? Do you have a solid front and back rest? Are load testing on calm windless days without mirage?
How many rounds do you have through the barrel when you test loads for groups? Some rifles require some degree of copper equilibrium in the bore before they start to group. With some rifles, when you strip all the copper out with harsh copper removers the rifle has to re-season the bore with some copper before it will group. I know that sounds like cleaning heresy but I've experienced it with some rifles.

I do not keep mine under max. I measure mine with modified case and bullet i want to run, then start .020 off lands. After powder charge found i play with seating depth. Has worked for me. Only time i dont mess with it is if loaded round is too long for mag and i need it to fit in mag.
735VB you have never mentioned cleaning, I brought up borescope because a friend that hunts bought a new 300 win mag Sako for his elk trip. He tells me it is now shooting a 12 -14 inch group. The sako rep tells him to clean the rifle. He doesn't believe the rep and when we bore scoped it it was full of copper. I had to prove it to him and he was still skeptical. I cleaned on it for about 30 minutes and noticed it still had copper in the top of the barrel, i guess gravity had pulled most of the copper cleaner to the bottom. I turned the rifle upside down in the cradle and cleaned some more. He shot the rifle the next day and it was back to 3/4 MOA. He told me he cleans it all the time with a bore snake. Some cleaning methods work better than others, look at the way you clean and the only way you can really do that is with a bore scope. K22 is exactly right, any good rifle with a factory load will shoot an inch or and inch and a half maybe even a little bigger but not all over the place. Scope, beading, fouled bore, lose rings or base bad barrel.

Depends on how your chamber is cut. Many factory chambers are pretty long. They're made to chamber any round one is likely to purchase. Conversely most ammo is loaded fairly short, to chamber in any rifle one is likely to find.
Example of chamber diff's: 308 Win, Remington factory barrel, trying to soft seat a 155 Match King (placing the loose bullet in the chamber with the case behind it and closing the bolt) would not seat the bullet at all. The throat on that particular chamber is really long. Replaced the barrel with a PacNor, now get at least a little of the bullet is the neck when doing the same thing (or rather, I did before changing the barrel to a 6BR.)
Do all of, the above "suggestions" THEN,.. IF, all else, "Fails" ,.. sell it, and,.
BUY, a Tikka,.. the 3 in my Family ALL shoot, Sub MOA ,.. repeatedly with, a variety of, Loads !
With, Minor modifications,. Higher Cheek rest, Trigger Spring, Check, "Free float" of bbl., "Lap" rings/ Loctite, then, carefully "break in", Barrel and,. go Shoot / Hunt !

Perhaps you’re simply expecting too much from your chosen equipment?
Accuracy and tiny groups cost money. There’s really no getting around that.

Ok I’ll toss this out thr, that scope is a turd and I can say that because I have one I had on a 243 truck gun that did the exact same thing your describing. Sprayed bullets making the target look like bird shot hit it lol. I would most definitely swap scopes or put that scope on another gun before sending the gun anywhere. They will fix it for free but if that turns out to be the problem I would go another route, I did. Screw me once and I’m good but not twice,, those scopes are notoriously known for this problem.
check out vortex scope! I had a diamondback and sent it in 3 times. After about 50 shots i had trouble getting it to focus. I gave up and went to different brand of scope and problem solved.
