    I have brass, dies, 1680 powder and lots of SMK's. I'm going to load a bunch of subs this weekend and shoot some at the ranch. H, when you make a 9" barrel, let me know, I want one of yours.

    Not these, messed around with a friends Whisper a few years ago, it's cool suppressed and FA but I'd rather have a 6.8 to hunt with.

    HTR, these are the same as everyone else's, it was a piggyback deal.

    OK, thanks, H.

    Agree, I will only run the BLK suppressed and subsonic.

    Man that is good news. I would suggest that you make up some cartridge chambering gauges ... they make life MUCH easier when learning to make brass!!! If I hadn't already had one made 18 months ago, ARP would definitely be the preferred supplier for me!

    Anyone ever tried using 6.8 mags to allow longer OAL?

    I am reading that the standard magazine has some trouble feeding the 300 blackout? I was interested in the cartridge as a supersonic hunting round, then I heard that the chambers are cut long to accommodate the 220 grain Sierra, and the thing about the magazines feeding the round. So I am still trying to decide what to do for my new hunting rifle.

    The 6.8 is a lot better as a hunter, the 300 is a "fun gun" unless you are attached to a special team that uses it.

    Hey C
    I've been looking into picking up a M17S and having it converted into either 6.8 or 300 blackout...but since Kurt passed on I haven't been looking as hard. What do you know about how easy/hard doing the conversion might be? I know the bolt would need to be custom made for a 6.8, while the 5.56 should be fine if I go the blackout road.
