No one is saying it doesn't happen; but rather IF the barrel is properly stress relieved AND there are no pressure points on barrel AND the action is stable within the stock, THEN there shouldn't be any shift.I had a Kimber mountain ascent in 6.5cm. I GUARANTEE there was a shift on the third shot if they were inside a few minutes. No question.

Stress relieved refers to heat treatment at specific temperatures to relieve internal stress in the metal that results from working it.Besides the trolling, this has been extremely informative for a FNG trying to step up his game regarding his rifle setup. Thank you for conducting such a test! What does stress relieved mean and how do you confirm if your barrel is or is not?
It would depend on how the fluting is done, heat from a dull cutter could certainly introduce stress and work hardening. In general, when done well, my understanding is fluting is not an issue.Is there some sort of consensus on whether or not fluting of any kind will affect the stress of a barrel ?
And is properly stress relieving more important in skinnier barrels than heavier ones?
If the gun has been scrubbed, I can see that as carbon likely changes the interaction between bullet and barrel.I’ve seen on a couple guns that the velocity of the first shot will be consistently lower than all the rest of the shots. I’m guessing it has to do with the expansion of the steel as the temperature changes. If the first shot is always slower, I think it would matter at distance.
We were using labradar on one occasion and a magnetospeed on another. The guy with the labradar says that gun is always about 30fps slow on the first. The 100 yard groups are fantastic, but I’d think 30fps wouldn’t show up at 100.
Has anybody else seen this happen with other guns or is it just an anomaly of a couple barrels?

Years ago I bought a really nice model 7 in 260
That damn thing would string shots about 5 inches over 5 shots but I loved the rifle and decided I was either going to fix it or **** it with my home solution stress relief method
I put about 50 rounds through it as fast as I could, the barrel channel even started to smolder and I had to douse it with water
But damned if that didn’t turn that rifle into a solid 2 MOA gun
My questions are this.
How does one determine whether barrels are properly heat treated and manufactured when purchasing new rifles? Examples would be typical hunting rifles that a guy might look at, Ruger Americans, Weatherby Vanguards, Henrys, Remington 700, Tikka t3’s, etc come to mind.
What about older rifles? How does one determine whether barrels were built correctly and what wasn’t on older stuff?
