Anyone shooting 6x45mm?

I have an irresistible urge to make an AR using this round. Just one of those things that may not be totally logical but still on the bucket list. Over the years, I've accumulated suitable bullets(from previous projects) and a die set plus plenty of 223 brass laid back.
There used to be someone machining and selling 6x45 AR barrels on the auction side but I haven't seen any for a while.

    Yes. I recently completed a build with a Black Hole Weaponry 1-10 twist 16" barrel.

    Awesome round....very easy to load for. I load 85 gr Nosler Partition for deer.

    The 6x45 was, at one time, used by benchrest shooters. And, did you know that it was once considered as a cartridge for the proposed SAW (Squad Automatic Weapon).

    Yes, I was aware that a very similar round was tested but don't recall the specifics.
    My intentions are to use a large supply of Hornady 80 grain SSP bullets which were left over from a short lived attempt to down load a 243. Since I have everything except a barrel, the project won't be too expensive.
