Lot's of variables to consider.
Many times when you clean your barrel, it shoots at least the first clean bore fouler differently than when it starts fouling up.
So if you are taking your can off to clean your rifle, you can automatically assume it's going to shift slightly.
If you're just removing it to remove it an put it on another host for a while, it should not shift your POI when you attach it to its original host.
I've posted this over the past decade, and it's nothing new, most of our platforms have a shorter heavier contour barrel. IF you think about physics a long thinner profile will flex easier than a shorter thicker contour. Fluting may help also if you look at a flimsy piece of tin vs. a corrugated sheet that is much more rigid.
Generally you get less POI shift, better harmonic stability, accuracy and precision with short/mid length heavy contour vs a sporter.
Also, I've had rifles that didn't shoot as well suppressed as they did without, If you are a reloader, most of the time you can fix it.
