I really don't think it matters at all as to what brand of 30-caliber bullet in the 150/165-grain size is used, particularly inside of 300 yards. (Assuming reasonably tight groups from the rifle.)
My father only used 150-grain Hornadys, and witnesses watched him make one-shot kills out to 500 yards. I had a 350-yard DRT with a 150 Rem Bronze Point, and a 450-yard DRT with the Sierra.
Hit the heart or the neck. The fun ends and the work begins.
