    270 Winchester vs 6.5CM vs 6.5 PRC

    I would like to know what some of y'all consider as an advantage to one of these calibers if you have a max range of 600 yards. I think 600 yards is a good maximum range for most hunting shots and thought, what is the advantage over a 270?

    A short action? What do I gain with that?

    Better B.C.? At 600 yards what do I gain with that?

    Over the counter access to ammo? 270? 6.5CM? I doubt the PRC does.

    Recoil? Looking at felt recoil data charts does not reveal any huge amount among them.

    Heck, one could replace the 270 with a 308 and what would the advantage be then?

    Here is some ballistics for you with 130 gr bullets in a PRC compared to 270 with 150 gr Long Range Accubond bullets. Of course the 270 will have more foot pounds of energy because of the heavier bullet.

    6.5 PRC / 130g Scirocco II @ 3050fps
    600yds = -46.6" Drop, 2331fps, 1568fpe, 14.9" drift

    .270 Win / 150g Long Range AB @ 2940fps
    600yds = -50.2" Drop, 2294fps, 1753fpe, 14.3" drift

    Not a pizzing contest here just an asking contest. By the way I am not a fanboy of 270 or any other caliber, I have 33 rifles in 33 different calibers and reload for all of them. I might be getting too old and not buying in to the greatest caliber fad anymore.

    I'm a .270 Fanboy and I think the grain difference may be the culprit for the bigger drop in .270.
    If both bullets were the same grain the results would be more similar.

      Yes I mentioned that.

        Just read the comparison since I'm at work and didn't want to be caught ;-)

          If you don't reload, factory ammo will in general be faster and flatter out of the 270 across the board. So you have more options to find something your gun really likes. There's that.

            Well buying copper creek ammo for the PRC will get the following options. I have some of their ammo for my SAUM and it has been very close

            140gr Accubond - 3000fps
            147gr ELDM - 2980fps
            153gr ETip - 2960fps
            156gr Berger- 2870fps


            The .270 has one advantage only. Over the counter ammo

              Bobby do think if both calibers are loaded to similar velocity and bullet weights would there be an advantage to the prc at 600 yards?

                I have not looked at bullets but I bet there is more of a selection for 6.5 in VLD.

                  All the cartridges mentioned are good. The 6.5cm does have about 2/3 the recoil of the 270, which is noticeable.

                  My favorite part of the thread is that you have 30+ guns in different cartridges. I think that's great!

                    There is but it’s not major. Honestly I like both but my saum I built for the short action on my lightweight rifle

                      Well I looked at recoil and the deal there is the weight of the rifle has to be calculated in as well. So I don’t know if 10 pounds of 6.5 prc and 10 pounds of 270 are far apart in felt recoil, probably the 6.5cm is less though .

                        The average guy isn't going to buy copper creek ammo, this kind of performance is more or less custom reload specific.

                        Compare fps for factory over the counter ammo that's widely available in both calibers, and the 270 outperforms the creedmore in real world hunting situations by a long shot. In Colorado it's garnered the nickname the 6.5 needmore for all the elk that have been wounded and lost.......

                          Well those aren’t numbers for a creedmoor it’s PRC. I would never say a creed was better and it could never hit those numbers

                          Copper Creek is same as ordering from anywhere else

                          If you need “factory”

                            weight for weight the 6.5 is going to drift less. That's pretty much it.
                            All three will kill anything you want with the same deadness.
                            Saying a 270 will smoke the Creedmoor in hunting results is a joke-- there's too much readily available data and experience to contradict that claim.
                            The 270 was made enormously popular on the back of mainly one influencer fan boy, despite pretty dismal performance, particularly during those years of rising popularity.
                            It may be the only round more hyped than the Creedmoor-- people just don't seem to remember that since their grandpas were the ones that drank the Kool Aide before they were born.

                              Honestly i think at he 600 yd max, there is basically no discernible difference, except there are more rifles loaded in the 270 and OTC ammo is more reliably available. That is likely going to change with the CM pretty soon though
