I use the Sierra Prohunter in my 300 Win Mag and I have taken two deer with it. The bullets did what they were supposed to do complete pass thru no bullets recovered. The first was at 226 yds and the deer ran about 25 to 30 yds. The second was at about 100 yds and it made just into the woods about 30 yds or so. My load is 72.6 grs of IMR4831, 180gr Sierra ProHunter, Win WLP, Rem brass. OAL 3.560. This load will always group under an inch. The point of impact hasn't changed in 10 yrs. The gun is a Rem 700 BDL.
