    6mm BR Norma.

    Have seen a couple of these come up forsale but not a lot of info about them. Does anyone have any experience with this calibre? What are your thoughts. Cheers guys

    I love my 6 BRX Barnard & my uppers using the BRX case, 6, 6.5, 308 & 338BRX

    The BRX is the BR reamer in another 100 thou, so bigger case

    Love my Barnard 6mmBR. what's not to like with tight groups at 600yds. My XP100 6mmBR pistol is also a tack driver. Also have a couple of its siblings in 7mmBR & 30mmBR in XP's. A great little case that really delivers.

    6BR is great. 1:8 barrel, AR2208, Small rifle primer and a 105 Amax. I had one that I ruined and am gutted about it.
    Its popular so you're not overly custom for dies and accessories.
    Its efficient and inherently accurate.
    Its fairly cheap to run if you don't lose too much brass.
    It won't feed reliably from a magazine in most rifles. I think the T3 might work better than the Rem700 clones.
    Its that good theres a website 6mmbr.com dedicated to it and other accurate cartridges
    Theres great bullets available. I had a good run with Hornady 105 Amax and 87 Vmax. The VMax was a great goat and bunny killer.
    Id get another in a heartbeat if I could justify it and had more time.

    The BR is amazing for its size. Not far behind a .243 despite being a far smaller case. The heavy brass and small primer allow it to run a higher pressures without murdering the brass.

    Mine is used as walking varminter and I've changed to 75 V-Maxes from 87s as the 87s weren't that spectacular on splat factor. You're burning roughly 31grs of powder which is only slightly more than a .223 but the performance gain is huge. Super accurate, low recoil and reasonably good barrel life. What's not to like?

    I did 22br
    From memory when doing the numbers.... I think 80gr 22, was equal to 105 6mm if it was 100 faster. That's bc values.

    Funny, I'm sitting here running through all of the 6mm options with the 0.473" bolt face right now.

    I also like the look of the 6mm BR, but I also really like the look of the 6mm XC and 6mm Dasher @Curtis27.

    What I'm liking about the XC - at least just from looking at the models - is that you can get stonking velocity with low pressures using slower powders, and hence (theoretically) longer barrel life.

    I'm doing a comparison document at the moment so I can get my head around them, and I'll post it up here later.

    I'm completely new to these cartridges and am using Quickload to see what's what. The only 6mm I've ever owned is .243, so if anyone knows something that I don't and it looks like I'm talking shit, please tell me.

    @Uplandstalker has just put together an XC, I'm sure he'll offer some first hand experience soon.

    I built a 6XC with a Pre-fit barrel on a Model 7 action. 26" 1:7.5 twist. Pushing 108gn ELD-m at 3135fps without pressure signs. 3178fps shows the slightest shine from the ejector.

    Keen to try some 110gn SMK as they appear to be about the best option regarding BC. Better than the 115gn DTAC's, but might require a 1:7 at stated by Sierra. Have read that plenty of folk at doing OK with them at 1:7.5.

    Currently have only fired 41 rounds in it.

    I'm running the 110gr SMK's in a 1 in 7.5 twist, 25" Bartlein. 6mm Creedmoor at 3,080fps. it's in a comp rifle setup so not running it overly hard. Shoots extremely well.
    If it's not a first round hit you need to practice more

    I'm also considering a 6mm BRA (Ackley improved BR) or 22 BRA or possibly a 224 Valkyrie. Wanting it as a LR varminting round with good barrel life. This is the key reason I'm wanting it, my Creedmoor barrel is for comp's and it's a 5 minute job to change barrels.

    The BR variants are quite attractive given the Lapua brass available and now MDT BR specific mags. Just got to get them in 10 shot rather than the current 12 shot...

    I've gone from 1:10 6mm BR to 1:8 6mm br to 20 br to 22 br and now 6mm BRX.

    Just fitted a magpull poly bottom "metal", shortened the follower and man does it feed well.
