    If not the 6.8 SPC II that then maybe the new .30 by Remington. Or I could just stick with my .308 POF. But I did read recently about the 6.5 Creedmoor that would fit in the .308 frame. Maybe it's time for a new poll. Or maybe I will just wait to see which endures. (I know I can't wait that long...).

    I don't say much about the 6.5 Grendal because I think that will be the Mac/Apple of rounds. Too much proprietary-ness holding it back. Well anyway should I turn this into a poll? I know they are different this is just for fun.

    I do want to hear about this new 6.8 SPC II. What is different?

    .30 RAR you can't beat .300 Savage performance out of an AR15.

    SpecII is a revision to the chamber specs for 6.8SPC, to lower peak pressures. It allows 6.8SPC to achieve something closer to (but still not meeting) its original velocity claims.

    What is *best* depends on what you want to do.

    For hunting in Texas inside of 300 yards - I like 6.8SPC just fine. I also like AR15s in 7.62x39 for the same uses.

    For social uses, where hicap magazines are an issue, I prefer either 223 or 6.8SPC.

    I'm very interested in the 6.8spc but not for any semi-auto, rather as an excellent mid-power deer round. It's already available in the Ruger compact bolt action, I'd love to see CZ chamber their carbine for it, and what would really be welcome is a light weight pump action carbine. .270 lite!

    Hopefully Remington will increase their push for the .30 AR.

    This is an attempt to bring a stronger hunting round to a platform that has a less than stellar mid sized game reputation. It will help legitimize the AR as a hunting and sporting gun as a tactic to fend off the AWB folks.

    A lot will depend if DPMS, Remington, and Bushmaster (They are all owned by the same company) can get the guns out to the public. They have the industry strength to push this over the wildcats and other rounds that don't have that type of strong backing. Question is when will they be caught up enough to apply this pressure, and will it be to late.

    I hope they do and that the .30AR cartridge is accepted and becomes widely available in numerous bullet offerings.

    gvnwst thanks for the link I will have to read that thread tonight.

    Honestly I would like to have them all and the 300 whisper too.

    rbernie thanks. So it is only a change in the chamber? So it can be loaded hotter but is safe?

    7x46mm Murray for me please.:)

    Let all AR15's specs/limitations behind and just start clean.


    Based on the Czech 7.62x45mm cartridge, necked down to 7mm. Drop in a 120-130 gr. bullet and you get everything needed in a combat cartridge.
    The brass can be made from new 7.62x39 brass and looks like Mr. Murray is able to get ready factory made brass:
    "I've got factory made 7x46mm brass from Privi Partizan. Their brass is made straight from long 7.62x39 blank cartridge case they make and has the nice thick Russian rim, I want."

    We passed by the seven by fourty plus millimeters twice. First time we got too powerfull cartridge for small arms, second time we went the exactly opposite, choosing the smallest cartridge we could get away with.

    Very humble opinion

    I do not reload or read ballistics tables for fun so my opinion my not be highly regarded. I have read about the 6.8 spc and the 30. rem which are my choices in that order. The 6.8 seems like it would be a great choice that will fall in to place with our current weapon systems and highly desired by our troops o the ground. The .30 I would like to know more about if anybody would like to educate me. All I know about it now is that it is similar to 30-30 win. Also what about the grendel I don’t like it but I can’t explain why may be just cause it looks funny to me. All that said please be nice I admit that I am a novice.

    Thanks Robert

    Take that grendel, neck it down to 6mm, and you have my choice. Pushing similar velocities as the 5.56 with much better BC. Makes for a hell of a round. Uses 6.5 mags. Seems like a great round to me.

    I don't own my 6.8 upper yet, but I own lots of 6.8 mags (in case of ban) and my 223 lowers, so I think I'm set for a bit.

    I <3 the 6.5 Creedmoor.

    now then, I voted for the Grendel, but if remmy starst pushing the wonder effects, and usage of the 30.ar, which does all that it does, within the ar15 envelope, including the mags, then I would gladly go this way.

    for those who don't know, the 30.ar is basically a 223 short case, straigt walled, with a 30 cal bullet in it, at about 110 to 120 grains. that would be some sweet action out to 300 yds.
    and for close up work, a great door/wall penetrator, if the zombies are coming.

    What's the difference between the .300 whisper and the .30 RAR?
  19. jerkface11

    jerkface11 Well-Known Member

    .30 RAR has close to .308 ballistics. .300 whisper is about like 7.62x39

    See the sig links for details on my favorite.

    I'm killing critters with a 7.62x39 at ranges that most 6.X ers would love to be able to claim.

    If building sumpin from the ground up you could go with something like this
    30PPC Largo

    Misinformation seems to be your thing, I'll fix this for ya too
