One of my F Class bud's was talking about chamfering the nose of his match bullets. On all of my 168's and 175 SMK's in 308, there is a little hollow circle at the tip, so I call them hollow points. After all, there is a lot of air space in that tip. Match bullets are not meant to be hunting bullets, there is no consideration for controlled expansion at any speed.
I did read an article, decades ago, about the most accurate 9mm pistol bullet. It was some research contract for the military. The hollow point was the most accurate, had to do with having the longest length between a pressure wave out in front, and the center of gravity. I assume it works similarly for rifle ammunition.
But, and this is a huge but, concentricity of the jacket, and having the center of gravity exactly in the axis of rotation are very critical for accuracy. If the center of gravity is out side the axis of rotation, that bullet will wobble in flight. And then, there is something absolutely no in print gun writer talks about: stability at distance. Heck, these guys shoot their rifles at 25 or 100 yards and then make predictions about hitting targets at 1200 yards, and more!. But they don't shoot their bullets at distance. And until I had access to CMP Talladega, I did not know that funnies are real
This was a bullet and a load I shot at 600 and 1000 yards, and I thought I was the world's worst 1000 yard shot. Shoots well at 300 yards

For decades I have been reading these jackasses in print tout the ballistic coefficient, or the trajectory of this or that bullet, and not one of them mentioned bullet instability at distance. And, this includes pistol bullets, I have loaded 44 and 45 bullets slow enough, they tumbled at 50 yards.
