I have had 75 gr Vmax keyhole from a 1 in 14" twist 6mmBR.... twist rate too slow.
I have had a .310" bullet keyhole in a .314" groove 303 Brit ..... bullet not getting traction on twist.
I have had oblong holes in the target where the wind picked up part of the target and bent it..... bullet hits target at an angle.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
