    .25-45 sharps isn’t a bad choice, but that velocity is for a 20″ gun. If 6.8×51 is going to be the path forward , short barrel performance in a easy retrofit is going to lean more toward something like .277 wolverine.

    Man… if only some 6mm option existed that worked in small frame
    ARs that helped provide effects closer to .30 cal and was already endorsed within the DoD for use …. We could call it an “advanced rifle cartridge.”

    If you’re limited to the 2.25″ COL of the AR15 format, I think the solution is going with a slightly shorter case to allow more ogive space for a narrower, lower drag bullet.

    For AR10/7.62 actions, we saw this with the 6.5 Creedmoor.

    For AR15/5.56 actions, something like a ‘5mm Creedmoor’ – 5.56 case shortened to ~5x42mm, with a very low drag 50gr .204 lead free EPR similar to M855A1. Capable of being fired at a full 62kpsi pressure unlike the fatter grendel/spc based cartridges.

    Berger used to offer a 55gr .204 VLD, with a G7 of .182, fairly close to the 0.190 G7 of the 77gr SMK 5.56, and way higher then the ~0.120 G7 of 55gr M193.

    What they want is 6mm Max.

    For the bolt upgrade they really went with virtually eliminates all “jamming issues”…
