Otherwise everyone would be shooting RPR's.
    Most guys going to a bolt action like a RPR are really expecting more than sub-MOA in my opinion...more like 1/2 MOA. I think they would be truly disappointed in the RPR if they cannot shoot smaller than 3/4 MOA consistently. They will chase and chase and chase and every once in a while, they'll shoot a good group every now and then. They will try different powders, primers, brass, bullets, into the lands, off the lands, anneal every firing, chasing the ammo combination that gives them the consistent 1/2 MOA group (or better). They will spend hundreds of dollars in range fees, and ammo components.

    What I am getting at, is they are already spending a good amount of money chasing smaller groups; it is just that they spend the money over a lot of smaller things. In reality, what might be needed is a $400-550 dollar barrel to replace the factory barrel...and if that does not help, they might need to look into whether or not it is the nut behind the gun.

    I would disagree that you need more than a barrel to make a RPR into a tack driver. I probably had the 3rd RPR in CA a couple years back when they first came out. Right out the box, it would shoot 1/2-3/4 MOA...not bad for factory. The gun was a 6.5 creedmoor. The gun would not do much better than that consistently. I removed the barrel and had a 6 Dasher Hawk Hill barrel made for it. The gun was a tack driver as you call it and there was no trigger upgrade back then for the RPR. It would consistently shoot 5 shot groups in a 3/8" group or better.

    The reason RPRs are not more widely shot in matches like the PRS is partly a gun equipment macho thing, IMO. The RPR is this entry level bolt action rifle and no one wants to be seen with an entry level gun at the competition level where you are traveling up and down the state or across state lines for matches and shooting for prize money. So, they buy Defiance actions, Surgeon rifles, GAP rifles, etc. They spin on Bartlein, brux and other custom barrels and buy NF, S&B and Vortex Razor GenII scopes.

    The RPR is a great starter rifle to see if you like that kind of shooting or not. Why dump $5-6K in a gun that you then decide is not for you, or you shoot once in a blue moon? If it is something for you, the next step is a good trigger, barrel and scope on the RPR. Then, if you think you are exceeding the limitations of your RPR at that point, then go custom. By then, you're at the point of no return and you are going to become a gear whore

      After reading this thread and threads on other sites, I went with an all steel (stainless) for a .338 Lapua build. I like the idea of lightweight and at one point, wanted a Christensen Arms gun but decided to go custom build. My other choice was Sako but I don't like the price for the accessories. I'd rather spend my money on other parts or ammo.

        After reading the description again at Cabela's:


        I remember something I read somewhere else. The AR-308 type barrels have a gas system length matched to the caliber to optimize for the lowest recoil. They include a gas tube cut to the proper length. So for AR's in 6.5 Creedmoor it's not just the light weight you pay for, it's the light recoil, which PRS guys are always hunting for.

          Light weight is NOT an attribute you want in a target rifle.
          Proper balance is FAR more important than the total weight.
          A 14lb gun that's tail heavy is harder to shoot well than a 18lb gun that balances properly.
          PRS shooters want weight for recoil absorption. This allows them to spot impacts particularly at the closer ranges. I agree carbon barrels are not ideal for PRS but I have shot my two of my 3 smallest groups through Carbon Proof barrels so to me they are hammers. I guess it depends what you mean by target rifle, I don't associate anything to do with PRS as "target rifle".

          PS, sorry for the Necro but I just shot a ridiculous 5 shot group with a 22" proof 6mm barrel in a Manners compact stock while breaking it in with Federal 105 Berger factory ammo. (Built this one as a hunting rifle for the kids)

            The primary reason for a CF barrel is the weight savings. It is noticeable since it's at the end of your rifle. I went with a Proof for my 6.5CM conversion for my AI. The 24" proof barrel is noticeably lighter than the factory 20" .308 barrel and shooting in various positions where you can't get to the ground or use any kind of solid support, that lighter weight is very helpful. Accuracy is just fine with the CF barrel. If I miss a shot, it will be me and not the barrel.

              Is it true (in your experience) that the Proof Research (or Carbon Fiber barrels in general) don't experience the first shot/cold bore impact shift as much as a traditional steel barrel?

                  I have a proof carbon wrapped 6.5mm barrel in my lathe right now.
                  I threaded the breech end and was chambering it and ran into a problem with the reamer.
                  Reamer maker overnighted a reamer today so I can finish in the morning.

                    Can be hit or miss. I am pulling mine from my 6.5saum. Won't buy another.

                      If there are other ways to lighten a gun, a carbon wrapped barrel will lighten it more.
