I doubt any bore can be that extreme. Twist rate...sure, but that's a bullet change....guts of the scope gone....yes! I'd check Hornady...minimum twist for 140 and then scope...throw it on another gun you know shoots!

How many rounds on original chamber? 6.5 is a pretty intense cartridge as far as barrel wear, so I have to believe the 6.5 Max is a larger (as you can't rechamber smaller) cartridge with greater powder capacity. I believe that the problem is mechanical more than bore size, or similar. We need more info on ammo, what was different the 3rd time shooting it.....rsbhunter. Note!!! Just read original post and saw load info, sorry!!!

After reading all the posts, I am going to bow out of this....between the rifle shooting ok, then keyholing, and "mushroomed" bullets, its beyond my level of troubleshooting.... I honestly hope you figure it out...I would be more bald than I am if it was mine!!!! Good luck...rsbhunter
Only thing that could cause this other than scope is oversized barrel. Keyhole, 14 foot spread? Shot 7-08 in 308 one time that did similar.

While waiting for the borescope to arrive - It might be good to clean the barrel well and run a clean, or even oiled, patch slowly through the bore. See if you can feel anything out of the ordinary. Like maybe a sticky spot of loose spot. Sounds like something in the bore might be tearing/deforming the jacket enough to make the bullet unstable.
I had a barrel with a loose spot so bad I could feel it with the patch. It is something that can happen with button rifled barrels. Vendor checked it. Vendor said sorry the barrel is outta spec and replaced it.
You would think the gunsmith would have found something like this though.....

You have to clean the living heck out of nitrided barrels at first to get the funky stuff out from the process, your probably gummed up and compromising the jackets and then tumbling the bullets.

@ GregH118,.. After Re-Reading, Your First Post,..
JUNK those, ELD-M's,.. As they are NOT meant to, "Handle" that kind of Velocity,.. in fast Twist, Barrels !
They were designed to be used at, 6.5 Creedmoor, Velocities or LOW Speed, 6.5 PRC loads.
Many, MANY, BAD "Reports" of Vaporizing at, mucho SPEED,.. OR, any amount of, Barrel, "roughness" on, the Accurate Shooter Site.
Like Bigngreen said,.. "Clean, the Piszz out of, IT " ( Try some JB's ? )
THEN, try,.. Hunting, Bergers or,.. ELD- X's !!
ELD-M's have a .023 Thick Jacket ( very, THIN ) vs the .037 thick Jacket of, the ELD-X or, the tougher Jacketed, Hunting,.. Bergers !

Your grammar makes it incredibly hard to take you serious, or decipher what in the hell you are talking about.
My God man! Enough!

True, but what would cause the bullet to mushroom before going through the target, unless it struck something first?
