    I’m new. I am hopefully smart enough to not blow myself up. But as a grown man I hold only myself for my actions... as stated I’m new so please be gentle the first time. The more I play the more I want to wildcat. I find myself going smaller and smaller. I started reading on efficiency and it appears wsm for example are more efficient than their full size counterpart. 17rem fireball appears to be more efficient if a tad slower than 17 rem. Wider shorter appears to be the most efficient. I’m also interested in shorter platforms that still deliver decent velocity. In the seventeens I even found someone that necked down a 357sig to 17.. 17-357RG. It died off quick but actually fit in a pistol. If, as a few articles suggest, fatter shorter cases are more efficient then why are there not more accepted examples? Why are wsm cartridges not more popular? What about cartridges like 22tcm? Or are these cases that look good on paper but for one reason or another just don’t in the real world?
     
    Industry support for a round will determine its popularity in the mainstream of things.
    The WSM rounds are fairly popular but support for the brass is hit or miss at times or at least it was when I was considering getting into the 7mmWSM.
    The 65Creedmoor and 6.5x47 Lapua are damn near the same round but the Creedmoor left it in the rear view mirror due to lack of support for the Lapua and only one source of brass and limited ammo offerings.

    So the science is there but it becomes a popularity contest?
     
    Yes, stubby fat is more efficient. But to a point. I prefer stubby fat with touch slower powders just for barrel life and ease on brass. I think a .22 Creedmoor is pushing overbore too much. The Valkyrie looks to be more efficient and much easier on barrels and brass.

    Nothing wrong with a hot overbore, just not my cup of tea.

    The science is definitely there and proven but for the general public or casual shooter industry support is king.
    For the wildcaters it doesn't matter what the big companies are supporting since they are innovating and make things themselves.
    The 30BR is a good example of that, I have allways thought it would be a damn near perfect short range hunting round for deer and hogs with almost unlimited barrel life but I don't expect any of the big companies to ever jump onboard and support it.

    I was looking for the .224 Valkyrie a year before it dropped. I was looking for a better feeding .22BR. I wanted to push 80-90gr .223 pills at moderate speeds out of a repeater but not toast a barrel in a weekend at the prairie dog town.

    Who knew I just had to be patient.

    I'm still considering one on a bolt action but think I will probably just use necked down unshortened 68spc brass. Been wanting to do that for a few years now just haven't talked myself into yet, if we start seeing some factory bolt rifles in 224V I may not be able to help myself.

    Exactly. Since I have all the stuff already, I’m just gunna do a .223AI since it will do 99% what a Valkyrie will. But if I started clean sheet? The .224 Valkyrie would be the ticket. It checks all my boxes. I only hunt Pdogs and want range with good barrel life and cheap reloading.

    The way it has caught on since being introduced and the factory support behind it I don't believe it is a stretch by any means to start seeing some new bolt rifles for it.
    I just need one more good push in the form of a good factory action to make up my mind.
    And like you said about the 223AI I allready have piles of 68spc brass both new and once fired waiting to be formed and loaded.

    What mag issues are you having and what brand ?
    I have a elander 6.5 and i was getting soft primer hits and half the empties would get stuck on the neck and ejection port. Upper and bolt are new but cheaper brand. I just got two 6.8 c mags but haven’t tried them yet and I’m broke enogh that I can’t grab ammo

    All though they are pricey the PRI are the Cadillac of 6.8 mags both the old non waffle and new waffle design. I've never had any mag issues with either of those or the ASC mags I have.
    By the sounds of your malfunction it seems more like you were under gassed and the bolt was short stroking.
     
    Nosler uses 223 bolt right? Faster but can’t run the heaviest unless in a bolt gun. Brass is harder to get, not as common?

    Nosler advertises it running them on an AR platform and getting like 2950 with a 77 grain bullet. 25% more case capacity makes it attractive for prairie dogs but your right.....brass could be an issue.
