So full disclosure, I'm not a rifle shooting expert like others on this board. I shoot rifles a lot, I build about 2 a year for myself and buddies, but rifles are my 2nd love after bows. Another disclaimer is I have always been a big cartridge, "no such thing as too dead" guy. Finally, I'm not big into handloading. I would love to get more into it, but I need another hobby like a need a hole in my head.
Ok, all those disclaimers aside, I built my father-in-law a 6.5 PRC last summer on a M700 donor rifle originally chambered in 270 WSM. That rifle has completely blown my mind and now I am in the process of building one for myself. That rifle paired with Hornady's factory precision hunter ammunition is amazing. We have shot hogs, whitetails, and a mule deer with the rifle and I cannot say enough how much that caliber impresses me. The recoil is very noticeably less than our 270 WSMs and 300 WSMs, however the performance on paper and game is comparable in my opinion. My father-in-law also says his 6.5 PRC kicks way less than his 270 Win, but his 270 win is pretty light too. We typically shoot our hogs in the head, but in Central Texas, the best test we could think of for the "tiny little" 6.5 rifle we build was to go find a 200+ lb hog and shoot him in the shoulder. I found one at 275 yards and shot him dead center in the shoulder... thing rolled like it got hit by a truck. I know there are TONS of super efficient calibers out there that do everything the 6.5 PRC will do, and I'm positive there will be 100 posts on here saying just that. However, in my opinion (I said my opinion guys) the 6.5 PRC is 2nd to none for guys like me that like the idea of stretching the typical hunting ranges a little, while maintaining light recoil, and having access to cheap factory ammunition. By the way I buy 6.5 PRC ammo for $34/box.
I'm not going to tell you that you NEED a 6.5 PRC, but I can first hand attest to how incredibly efficient the round is regarding trajectory and energy delivered vs recoil. One thing I will say is building 6.5 PRCs are cooler on some rifles than others. The 6.5 PRC is a cool simple build on some platforms, difficult and expensive on others.
One last thing I want to note. I have been following the 6.5 PRC for a little over a year now. I don't have a crystal ball regarding what factory ammunition will be available in the future, however it is amazing to me how much traction the 6.5 PRC has picked up over the last year. A year ago when I told my buddies I was starting a 6.5 PRC build, the normal response was, "a what".. "you mean a 6.5 Creedmore???" Now people respond more along the lines of "o yeah I'm thinking about building one too," or "man I keep hearing about that caliber seems cool," or my favorite, "why did they even do the Creedmoor if they were working on that?" (Creedmoor fans don't attack me its just a quote)
