New ladder test results.I have conceeded, New barrel is needed.Last post update.

Ladder testing isn't working.... so try something different.

Start at mimumum and working to max in one grain increments. Seat the bullet .010 off the lands. Load 5 of each and shoot 5 shot groups. See what it tells you. Maybe something will jump out at you then.

I would have to agree that 200yds just isn't doing you any good for a ladder test. Consider OCW test at 200 or as per jehunter recommendation and shoot 5 shot groups to search for a node.
 
Maybe some W780 or 4831 , they are usually obtainable.

Mind you it is a pretty short barrel to get a nice complete burn.

I am kind of leaning in the direction of powder speed ,a rifle can't be that bad.
 
I'd see if you can find a borescope and give it a once over and really look at the throat and crown ! Had this issue with a 6.5x284 and it boiled down to the crown on mine
 
Biggest thing I have seen affect my Savage rifle in the XLR chassis was action screw torque. My tack driver turns into a scatter gun with too much torque on the action screws.

It's free and worth a try. Mine is a short action and if I remember correctly is at 35 in/lbs. I have read of a few people taking their torque wrenches to the range and shooting groups and adjusting torgue in between to maximize accuracy.
 
I read once there was a sequence for doing this on Savages.

Anybody remember reading that or seeing it?

I'm assuming there was no skim bedding between the action and the stock? if so, I'd start there. Make sure there really is nothing touching around the trigger and all that while at it...

I'd also just put a good bi-pod on and get on the ground, and perhaps also try without the muzzle brake as last resort if you haven't already.
 
I appreciate all the suggestions, however in my mind I feel that it is something bigger than what many of the smaller tweaks could be.

Here is some of last years targets after ladder testing, groups shots after a suspected node was found,just examples, nothing was ever duplicated:







 
Bottom left target shows promise but you say you could not duplicate and it was just a fluke?

From all I have seen in this thread it seems to me you are applying lipstick to a pig...Can get very frustrating trying to find precision when the basics are not in order.

A precision rig can almost get boring as in everything you feed it groups well...Then you tweak to squeeze the most out of the components you want to use.

I find accuracy is easy when all the basics are in place...You may want to cut your losses and frustration and start over.
 
Looking at the bottom two targets, the 92 gr target is crap, the 91 is much better. I would try backing off another gr. The 9" twist may be too fast for that velocity.
 
Those are just examples, I had much lower charges , and much worse results.

Took a look at external stuff on the rifle this evening.

No copper on the brake.The crown doesn't show anything funky to me.

There is one land that seems to have a wear area parallel to the land/grove , seems to be touching the land on either side right in the grove.Probably nothing but who knows ,you can see it in photo 2 on the very bottom side of the bore, here is the pictures:



 
No resistance just haven't got there yet , just think there should have been some patterns or consistency with all the components tested so far.Just bloody don't know which way to go.

Spend more on testing , or spend on hardware?

After checking all the comments to date, why the resistance to testing IMR4350?
