    Thought I’d add this to the thread @Wingman if that’s ok? May be useful data for someone.

    Found a good load for my 6x45 today. 18” barrel 1-10 twist.

    70gr Ballistic Tip
    BM8208
    Winchester case
    RWS primer.

    I’ve settled on 26.3gr, as a max useable to keep case life ok. No need to push it, velocity is good. Book max is 27gr, and very very hot in my rifle. At 26.8gr I was getting 2950fps but stiff extraction and very flat primers.

    A little more info for those interested in the 6x45.

    I cut the base off a few different 6mm projectiles, and melted the lead out in order to measure jacket thickness. I also
    Measured the hollow point left, as it will also indicate the rate of expansion on impact.

    Sierra 100gr Pro Hunter: 0.028” jacket 0.065” hollow point
    Rem 100gr Core Lokt: 0.026” jacket 0.070” hollow point
    Hornady 87gr SP: 0.019” jacket 0.095” hollow point
    Sierra 85gr SPT Varminter: 0.019” jacket 0.065” hollow point
    Sierra 85gr HPBT G.K. 0.019” jacket 0.050” hollow point
    Speer 80gr SP: 0.020” jacket 0.100 hollow point

    I’d be interested to see the figures for a few others (that I don’t have)
    Sierra 70gr Match King
    Sierra 70gr HP Varminter

    Thats interesting as I use 8208XBR exclusively in my 6.5TCU Rifle, so not quite a 6x45 but I use 26gns of 8208 and 123 ELD-Ms or SSTs or lately 130gn RDFs
    Velocity is 2550 and thing shoots real good out to about 700m, past that it loses its lunch a bit.
    Might try a 6x45 next time or 6TCU if I can find a reamer maybe

    More success with the 6x45 a couple of nights ago. Took this yearling stag at about 150yds with a 70gr Nosler ballistic tip launched at 2950fps. To say I’m stoked with the bullet performance would be a bit of an understatement…. Went in tight behind the left leg, and out 3 ribs from the end of the rib cage on the other side. Great expansion and internal damage, yet still tough enough to get all the way through. That tapered jacket and thick base certainly does the trick at 6x45 velocity. So good in fact, this is the only bullet I will hunt with from now on!

    Also came up with the best consistent load so far, using AR2219. Gave it a go after a mate mentioned that he was getting great velocity and accuracy in his 6x45 with the 75gr vmax.

    18” barrel:
    70gr Nosler
    24.6gr AR2219
    Win case, federal 205m
    2900 fps, and has the headroom for a bit more pressure.

    so reading this.....thought came to mind???? the mighty 22-250 is a 6mm ??lee navy??? necked down

    so its a case with capacity you asking in barrel diameter you asking.....in length you asking

    Haha - after posting that I got a 6mm Crudmore built (which is the same as 6mm/250 Savage AI). I'm currently sitting on a Ruger American action with a interchangeable magazine system and a barrel nut,with the 1x16 thread being fairly common I'm planning doing some playing with the "small" 6mm,6.5 and 270's

    yes and I went looking and see 22-250 based on 250-3000 savage..... so a 6mm version would sit in middle of other two.

    I believe the myna series of cartridges were one of the first to really take off.

    nice to have the gear to make something different without it costing a fella an arm n leg.

    wont do anything that rifles I already have wont do just as good but one day I would like to make up a 22hp savage with .224 barrel and I reckon a single shot bakail would be perfect to re chamber.
