I am wondering why this comes up from time to time.
I can see it being useful for shooting varmints and hogs where a hunter may engage multiple targets. I can see it for poaching...though no one will say that is the intent. Same for SHTF and addressing two legged varmints.
But why would someone hunting deer (or similar game) want a subsonic platform?
Seems like a lot of companies offer subsonic .300 BO. Just checked on Ammoseek and there are three pages of listings for subsonic only. (BTW, four pages of listing for all weights of .300 Win Mag). Are these targeted to the mall ninja's or do people actually hunt with them?
If velocity needs to be kept in the 1000 fps area, wouldn't a .45 ACP carbine be a better choice than the .300 BO?
