Almost forty years ago I used some Hordnady 175 spitzers. I hit a deer in the shoulder about ten yards away fired from my 7mm-.300 Weatherby. None of the bullet entered the chest cavity. It turned so I shot it at the base of the tail dropping it. I then put one in the back of the neck.
From then on I used Nosler 175 and 160 Partitions until the Barnes X came out. I used them up to last year. Next season I will be using G.S.Customs for everything. Specifically I will use 85 grainers in my .257SLR. I am hopping for 3,800 feet per second. My most accurate groups and lowest SD's in my .375 and 7STW came while using them.
