    My spotter TDT burned all his hunting funds this year before we got to our pig hunt so I have my year's pig hunt money spare. I've been wanting to add another barrel for my MVP. Something with more bullet mass that I could get to reliably take down the 500m rams in silhouette competition and that would hold its own against 6CM/6.5CM/.260/6XC etc... but without so much barrel wear. The bigger 6's take 40ish grains of powder, the 6x45 only fits about 25 grains and I was wanting something in the middle, maybe 30-35grains.

    Enter the .22Nosler. Built on the 6.8SPC with an improved 30deg shoulder, 34 grains of case capacity to the shoulder, .223 case head thanks to a rebated rim and feeds from an AR mag. So, why not go big ups to Brooklyn and neck it up to 6mm and throat a barrel for long seated 105-110gn VLD's. I can get those pills going 2850fps with 32 grains of Benchmark in a 6BR so I should see similar speeds from the .22Nosler case.

    I've put a ping in to BlackHoleWeaponry to see if they'll cut something like that for me. In the meantime, grabbing more Dillon stuff to speed up my reloading.

    Let us know what you think of the round. What do you think about 7mm Valkyrie AR or 30 Remington AR? Too exotic? Not the performance you are looking for? I'm just throwing them out as ideas that fit in the .223 sized action but don't know a lot about them.

    the 7VAR and 30RAR won't fit the .223 bolt face which would make for a lot of niggly little problems. I already have a 7BR which is a kitten to shoot but it's in the heavy gun class and shoots too well to mess with.

    I thought about 6.5 but I really want the 6mm. It'll ring some rams where the 6.5 wouldn't but it'll run 6's a lot faster. To stay within bolt thrust limits I have to pull pressures down from my normal captain-insane-o levels so there's only so hard I can push things.

    Early reports are the brass sucks on the 22N, one and done (on factory ammo!). 30RAR ain't no brass left, and Remmy ain't making anymore.

    Single load or repeater mandatory?
    What about a 6mm-222M or 6mm-204R?

    6x45AI or 6TCU gets you a couple-three more grains of powder. Plus near straight wall ain't converting much of it into bolt thrust.

    Only other option is to open up the bolt face a little and go Grendel/SPC/PPC.

    I'm not getting much response from BHW right now about the 6-22N so it might be a non-starter. 6TCU seems like a good way to go. Gets me up closer to 29-30 grains of powder.

    I can get over 31g of ball powder in mine (6TCU) with light (55g-58g) varmint bullets at 2.325"ish OAL on .045" freebore. You'd need .090"-.110" freebore for 105-107's.

    What's the skinny on the 22N brass ? Is it the shoulder, neck, body or head giving the trouble ?

    it's the web unfortunately. They're loosening primer pockets like it's on sale.

    yuuuup. All reports are SSA brass is weak at the web. Primer pockets loosen fast.

    So who makes tougher 6.8 or .35 Rem or .30-30 brass than SSA ?

    What I'm thinking is a work around to get by until they get the hardness issue straightened out

    Chuck up a 22 Nos die in the lathe as a case holder, set the slide and cross feed stops and turn rebated rims on a few hundred 6.8, .30 Rem or .35 Rem cases.

    Lee makes those nifty hand presses with the lock-n-load 1/3 turn quick change die head and they are affordable. That would make getting the cases in and out of the die a cake walk. Shouldn't take more than couple hours to turn 500 good cases.

    Hornady and S&B make 6.8 brass. Federal used to with the XM68GD contracts but I don't think that they were ever resigned. I'm not sure how it would last though since the pressure may likely be higher in the 22 Nosler.

    Lastly if you didn't know, SSA was bought out by Nosler.

    It's looking like I'm going to have to wait a while and see how the whole 6-22N thing ends up working out. For now I'd have to buy a blank and have it chambered. BHW and I are still going back and forth.
