Also as OB said, the wind will change, for better or for worse. Don’t fall into the trap thinking that the 6.5cm will “solve all your problems”, it’s just fractionally easier to use (compared with similar sized cartridges) under adverse conditions. Emphasis on the word FRACTIONALLY here, quite insignificant at 100m (in like-for-like setups, shooting optimal loads). Bullets still get knocked at 100m, particularly noticeable from a fully supported position. Crunch the hypotheticals in the Strelok Pro app and see for yourself.
You’re probably on to something with your identification of S&B, but from my experience S&B factory has never been something to write home about. Just keep shooting, things you think are important and relevant now will change a lot the more you shoot.
Oh and no, your barrel is fine. Just keep treating her with respect. Brush forward only and let the chemicals do the work, over mechanical intervention. Less is more.

That is 10% are the highest quality, examples of these are what is sent to professional reviewers for glowing reviews.
80% are of good merchantable quality and the purchaser of these is quite happy in the belief that he has something equal to the upper 10%.
The remaining 10% are what people sometimes grumble about on forums.
That was today's dose of cynicism.

Regarding Hornady ammo, it would appear in recent times the gloss has worn off it being marketed as premium high accuracy ammo and thus priced. I know of one instance of a refund being given to a moderately large purchaser.

I suppose that it is possible that one or more of your fasteners could have loosened while you were shooting. Your scope and mounts particularly, rather than the take-down bolts, which usually these days are threadlocked.
Do you still have your targets? Take a look at the "shape" of the poor groups, ignoring horizontal dispersion. Is the vertical dispersion greater than the horizontal? If so, it could indicate problems with bedding and/or fasteners. Bench technique is probably not an issue, although you might be tiring.
Cleaning is a whole nuther subject I have my methods with BoreTech products but it is also about how you use the tools.
Let us know how you go mate

Pretty much right on 3.5 inches horizontal and vertical over 5 shots with the Hornady.
S&B was fairly consistently around .75 to .90 MOA going by eye in 3 shot groups.
It would be good if I could upload the photos, damn.

Always use a Bore Guide when cleaning. Don't ever reverse a brush in the bore. Don't force or go too fast with a brush (slow and easy).
As mentioned, first patch with a carbon cleaner and push it forward then out and replace maybe do another. Just gets rid of the crap first up.
Don't over clean, don't be too aggressive with the cleaning.
