    I too was considering having a barrel made in 30 HRT caliber...

    It's a fine wildcat, however, It doesn't provide a substantial
    Improvement over the x39mm...with new commercial steel
    cased ammo in bulk so cheap, as well as bulk brass cased
    ammo at $7-$10 per box in bulk, I figured building a x39mm
    upper was going to be much more cost effective.

    A quality chambered barrel blank is going to cost you at least
    $300, and then send it to G'smith to have it threaded, fitted,
    crowned etc. is going to be in the $150-$200 range.

    A decent quality complete upper/kit in x39 cal. can had for $450-$500 delivered.

    So it really depends how much you want the 30HRT wildcat, and
    are you willing to spend the cash & time needed etc.

    Good Luck.

    Your right, After more research it's pretty involved getting one up and running. I like the 30 RAR but i don't know what remington is planning to do with it. They can't seem to get there act together on anything.

    The 30 RAR is another great round, but as usual Remington has
    dropped the ball once again...They have yet to properly market the
    round and more Importantly have failed to offer any brass to
    reloaders/hunters/target shooters etc.

    I would love to use the 30 RAR case as a basis for a .264/6.5mm
    wildcat version for the AR-15 platform...but alas, without good
    and reliable souces of brass it's a dead horse at this point.

    It has real potential @ 44 grains of H2O and would make a great
    overall round and a greater wildcat round in 6mm, 6.5mm & 7mm !

    Yep, A 6.5 would be awesome!!! I think i'm going to build an Encore barrel in 30 RAR. I have a 30 cal Green Mountain blank that is just sitting there doing nothing. 4D has the reamer for rent for 30.00. HUMMM

    Here is the first thing that came up when I googled 30HRT.

    Definitely like the idea of this round.

    It's funny to me that it took the standardization of the whisper as the blackout to finally give us a good supply of factory produced barrels that we can rechamber into HRT's as the very reason the HRT exists is to solve the subsonic lack-of-gas problem that subsonic loaded carbine gassed whisper barrels have.

    I had the first two sets of headspace gauges ground for it, one set for Marty and one set for me...

    The solution to that problem - and I agree it was a problem historically - was to use powder that is more compatible with ARs. A1680, RE-7, and H4198 are some examples.

    Agree..if you are looking for a 8 or 7 twist barrel. If I start building 30 Herretts they will be for hunting, 11 twist and 5R, 16" mid gas.

    A carbon length gas system on a 16-inch the 300 BLK/Whisper is only useful for guns that are set up to shoot primarily supersonic loads. A properly set up 16 inch barrel with a pistol length gas system will shoot subsonic loads with bullets weighing 150 to 240 gn. It will also shoot super sonic loads and only give up about 25-50 fps to the carbine length gas system. Moreover, a correctly designed gas system will not need an adjustable gas block either, and will work with powders like 2400, W296, H110, A#9, Lil'Gun, 4227, A1680, and 4198. Did I leave one out?
