Well..
There's anal, and then there's... me!
So I took some data and plotted the bullet drop rate for .357Mag, .223, .30Carbine, .308 (147grain), 308 (180 grain), and the .17HMR.
It seems to me, the 308 is as versatile as I first thought. With the 147gr, you aren't loosing a lot of bullet drop compared to the .223, but you get a LOT more mass and umph. So I figure, 180gr for deer, 147-155grainers for Wiley. And it's good out to 1000 yards (assuming I can shoot that far).
Someone told me the 308 (and 30-06) is probably the most versatile round from a North American needs perspective. I see why now.
But as for Pdogs, I'll probably go with the 357Mag out of a rifle at first.. Of course if I'm not hitting with that... time to move to the 308!
El Rojo...
I have 2 lower AR15 receivers. I shipped them out of the state, because I don't need to become "tactically broke" from making "tactical rifles" out of both..
