    I just cannot get behind the idea of any rounds between the 6x45 and 300 BO when we have larger capacity cases that work in an AR (6.8 SPC or 6.5 G).

    Admittedly, 40 years of being intested in guns leaves a person a little jaded when it comes to the next new hotness round.

    It is all trade offs.

    Advantage of cartridges like the 6.8 SPC and 6.5 Grendel is more case capacity but with the down side of lower magazine capacity and/or proprietary mags.

    The 25-45 Sharps is a 223 necked up to 257 and probably works well in the AR. The drawback to the Sharps is bullet selection. Nothing heavier than 85ish grains can likely be loaded to 2.26" for magazine.

    6x45 is in the same boat. Bullets of 75 grains or so is as heavy as can be loaded before overall length becomes an issue. No real advantage over the 223 with a 75-77 bullet at that point. Any slight advantage in BC is probably mostly academic given the 2.26" length restriction.

    And this is the drawback to the AR as a whole. Regardless of case the cartridge is still stuck at 2.26" or thereabouts.

    “The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."

    Excellent post. The wide selection of heavier bullets in the .223/5.56 really put the nails in the 6x45 coffin. When a standard .223 bullet weighed 50 or 55 grains, the 6x45 made more sense.

    I hope the 6.8 hangs in there, because I want one for no really good reason.
