From what I have read, some people have misconceptions. It isn't a long range caliber.
In subsonic loads with a silencer, I've been told by people who hunt hogs, that the hogs can't here the shot, and the herd just stands around, and you can pick them all off quietly. Under 100 yards, that it the reason for the 300 AAC.
In hot loads, it has 7.62x39 ballistics, and downrange at 150-200 yards actually more accurate.
You shoot heavy bullets to make it subsonic, and lighter bullets like 125 gr or 110 gr for supersonic loads.
Brass can be made from 223 brass, and 30 cal bullets are easy to find.
I wouldn't shoot a deer over 100 yards, but in a stand over a small greenfield or in the woods.
That being said, I like the 6.5 Grendel best, followed by the 458 Socom for actual big game hunting. There again, the 458 Socom is limited in kill range, more like the 45-70.
I also like the idea of the 6x45, not as powerful as a 243, but could hit fairly hard and legal for deer in most states and it too uses the 223 brass.
