I have found that Sierra Gamekings are very consistent in not only appearance but shootability. They are my first choice and have proven to be very accurate out to 500 yds. in several of my rifles. I would consider them 'match grade hunting bullets'.

I have shot A Maxs, Match Kings and didn't find them to be more accurate in my rifles than Sierras GKs. Never tried Bergers.

In the tests I have seen over the years bullettip deformation doesn't effect accuracy until you extend the range out beyond 200 yds. or so. Don't know as I have never experiemented myself. Nowadays plastic tipped bullets being the craze, I believe they are much more identical than they ever have been.
