Indeed, this is a very true statement.............While I do not hunt deer, and retired from other hunting for a few years now, I load and shoot 300 BLK quite a bit, and we designed a serious bullet for it, mentioned above the 100 FB Raptor from CEB. Its just plain WICKED........ it is very popular with some of my friends throughout the country and very popular especially with the kids. I have a friend who's 10 year old has taken deer, alligator, and even a large black bear with 300 BLK and the 100 FB Raptor with extreme success........ and there are many many others that have been successful with it as well....... I have not one report where anyone had to trail or have a big followup, all the reports I have have been DRT on the spot. Even the black bear was DRT.............
I don't do subsonic in 300 BLK. The load I use with the 100 Raptors runs the bullet at 2550 fps in most all 16 inch guns, 10.5 inch guns run 2370-2390 fps.........
I see someone mentioned the 110 Barnes TAC, this is also a very good bullet. While I don't have any of my folks that have used it in the field reporting back, it tests very good here, and I would not hesitate to recommend it as well. I don't think its as good as the 100 Raptor for extreme terminal performance, but its still a very good bullet, and most of the time easily available.
Below is the 100 Raptor without Talon Tips loaded in 30/30, with 300 BLK and 308 Winchester alongside also loaded with 100 Raptors that are Talon Tipped.............
