    bfoosh,
    I was able to pull up data - The 85gr MB is 1.068 long and the 80gr Sierra is 1.090 long.
    In looking at the picture - if that is the actual bullet - it appears to be as I thought. Long bearing surface with a smaller radius ogive. This is very reminicent of the 80gr Hammett's that were made by Clarence Hammett back in the late 90's/ early 2000. He ran a drilling company in LA and made bullets on the side. He had a fair amount of success with a heavy bullet (80gr) that could be loaded to mag length. He used a rebated boattail on his. They were finicky, but they shot well with the right load. We used them at 600yds through a mag and they would easily hold the 10 ring. They were a bit sensitive in the wind though. He got out of making virtually all bullets except for custom .17's. I don't think he is in business anymore. This Barnes 85 looks earily similar. I will see if I can post a pic of the Hammett tonight - I still have a few boxes gathering dust somewhere.

    I am still curious that they used a 12 twist barrel and show the velocities that they do. What kind of chronograph do you use?

    Looked at the tests - thats a lot of shootin' - not to mention bbl life!!

    Curious - where did you get the 80gr Federal Gold Medal Match? Is that the ammo that is loaded with IMR 4064?

    That ammo is interesting - and there is an unique back story to it. The XM223M1 was a factory produced load for the USAMU back in the early 2000's. It is loaded with 80gr SMK's in their Gold Medal brass with Fed 205M Match primers. The powder is IMR 4064. The AMU never used it in competition or really at all for that matter as the charge weights were all over the place. They vary by 1 -2 full grains. I find it amazing that this stuff found it's way to the commercial market. But then again, it really isn't surprising. The ammo will shoot really well if loaded cartridges are sorted by weight. Some of the batches with higher weights will run really well at range (600yds).
    The OAL is specific to the throating used by the AMU in that time frame. An 80 SMK seated to .010 to .020 off the lands in an AMU generally runs 2.500". The original 500rd cases had the warning printed on each end; "FOR USE IN USAMU CHAMBERS ONLY"
    Mind boggling that they are selling it for almost $20 / box. Yikes. Buyer beware. I have multiple cases of the stuff and I pull it apart - recycle the primed brass and use the bullets in other loads - my wife's garden gets the 4064.

    Respectfully as well....

    "Out of curiosity, what are you loading for powder? CFE223 or A2520? I'd be interested to understand how you got those velocities from a barrel 4" shorter - have you verified your chronograph?"

    Both barrels are 1n7 twist. Factory ammo fired on the same day, etc.

    Those are recorded velocities from the Barnes OEM 5.56 factory load.... and the 16" is a V7 "Match Barrel" ( http://www.vsevenweaponsystems.com/c...atch-barrel-16 )

    The 20" is a cheap PSA SS CHF match upper... and frankly its velocities are, in general w/ 75gr and above, about 100fps slower then most of Molons velocities from his threads.
    It still shoots good, but is certainly a "slower 20" barrel".

    Link to Factory load...http://www.midwayusa.com/product/463...-otm-box-of-20

    "Also - if you have the chance - how long is the bullet itself? How long is the bearing surface?"

    I will have to pull one to check, It might take a day or two to do so.
    I will weigh the powder charge, for the sake of weight info only.

    His measured OAL of the 85gr bullet ( 10 round average ), 1.064" long
    Attachment 35538

    I will add that the Ogive of the 85gr is closer to a 55gr then a 75-77gr.
    I snapped a quick pic last night in the loading room of some of the 224 bullets - note the length and the shape of the ogive on the heavier bullets - specifically the 75 and up. Take a close look at the 80gr Hammett - very similar ogive, but with a rebated boat tail..(to the 85 Barnes)

    Just ordered 200 of these from Barnes direct. For some reason, I didn't think they were available.

    (Geez. Re reading some of these posts has me scratching my head on which powder to run.)
