I recently thought about jhaving a .300 PRC from watching Piet on Impact Shooting with his .300 PRC go for about 1.6 km. Center hits to almost 900 meters but the wind started kicking his butt past that.
"Long Range Shooting Manual" was written by Ryan Cleckner, formerly sniper team leader in the Rangers 1/75 for some tours in the GWOT. In service, he shot a .300 WM. From about 500 yards or less, and most engagements were under 300 yards, he could dial elevation for distance and then hold left or right edge of the target zone into the wind and get a hit. To be fair, this is what he called tactical shooting. It was not about a center dot hit or winning points. This was about getting a big ouchie on an enemy agent.
Then, he got into the .300 PRC. It did what the .300 WM did but with less drop. Now he hunts with it and has even expressed a wish that the military would adopt it into their various sniper programs.
I like the 7 PRC because it will take mule deer quite nicely. And, with my cushy recoil and my ASR brake, it feels like a pushy, not jabby, .308 W. Totally comfortable, so you can afford the time to get good and comfortable with it.
I do know that with .300 PRC, recoil management will be key.
