Any theories as to why the POI?
I am guessing something to do with barrel harmonics.
IIRC, when add-on brakes were advertized years ago, one of the features was supposed to be no POI change. Not so for mine. The change is to elevation and it is substantial.
Seems a bit odd as the bullet should in theory be gone before the gas pressure hits the brake, unless harmonics are involved due to the extra weight on the muzzle.
Does that seem to make sense?
I absolutely believe it is barrel harmonics. Take a look at the adjustable brake and you can see the effect of harmonics and how it can be controlled. By the way did you know the patent holder on that brake was told by Savage to go pound sand when he filed against them. There words were our pockets are deeper than yours. The target shooters use all kinds of tuner to adjust harmonics.

Of the piles of rifles you have tested, do you remember if those with freefloated barrels are effected more or less than bedded barrels?
Most were free floating as that was what the company sold. If a gun wasn't going to shoot it was most likely to be a fully bedded or pressure point rifle in a wood stock. Fully bedded or pressure point in glass stock no problem if put back in the stock correctly.
Of course there were rifles that just wouldn't shoot no matter what you did to them, they were just lemons.
