    I'm pretty much ready to bail on 224 Valkyrie. Almost 1,000 rounds in, Im still chasing consistent half inch groups ( bolt gun, 100 yds)

    Looking for about 2,900 + fps using high BC 80.5 and 85.5 Bergers ( already got a supply)

    Thinking:

    22 Creedmoor

    223 Ackley Improved

    22-250

    What else? What you recommend ?


    Inended use: PRS type accuracy out to 1,000 yards + shooting steel.

    22 Dasher would be a solid choice.

    Last summer I got my 22 creedmoor up and running and I'm loving it. I use it for longrange groundhog hunting. I'm getting a little over 3500 fps shooting sierras' 77 gr. TMK which worked real well out to 875 yds. No fireforming like the Ackley improved cartridges which I like, less work. Anyway, that's my recommendation.

    I'm all for things I no longer have to fireform for so my vote would be 22 Creed, 22x47 or maybe 22 BR.

    Doesn't the Valkyrie use that weird .420 size bolt face? If you plan to use the same action you'll have to change bolts or if it's a Savage, bolt heads, if you want to go down to the 223 size bolt face, won't you?

    22BR WOULD A GOOD CHOICE BUT THE LITTLE 223 ACKLEY STANDS IT OWN GROUND AND DOES QUITE WELL FOR ME BUT THERE ALOT OF ROUNDS OUT THERE TO PICK FROM BUT I GUESS I'M OLD FASHIONED

    I forget what twist you said your 224 is, but I get this at 100 yards with my AR 224 and a 6.5 twist with 95grain SMK's and Rl-15. My 5 shot groups are the same at 100 yards and remain under 1/2 MOA at 200 yards. This was a powder test from 23.2 to 23.8 grains, going up .2 for each group. RL-15 has been the best and most consistent of all powders with this hard to tune round.

    If you have a 7 twist then you probably won't be able to use the 95 grain SMK's.

    Garandman -

    Howdy !

    What I did was neck .35 Remington down to .224” calibre.
    I first ran the wildcat in a 24” 1-14 SS 5-groove Hart as my idea of the perfect anti-groundhog round, shooting Hornady 55SX. The rifle also worked superbly for local target shoots.

    Got into the 500 yd club on a 510yd groundhog kill, shooting a prototype of Hornady’s 55 “V-Max”. When the barrel started to keyhole some shots after years of use, I re-barrelled by chambering a K&P 28” SS 1-8 in my .22-35 wildcat. The intent was to give myself another dual-role’ varmint/ target rifle; this time.... capable of 1,000yd use. I shot Hornady 75”A-Max” in the rifle, exclusively.

    .22-35 has case capacity between that of a stock .22-250 and a .22-250AI.
    Case oal is 1.920”..... same as the “Creedmoors” have these days.
    The .35 Rem rim diam works just fine in my Wichita WBR1375 action, which is also outfitted w/ an M-16 style extractor.


    Another wildcat chambering that can be had is:
    run a .22-6mm reamer in “short”, for a nominal .466” base diam.
    7 X 64 Brenneke is used as the parent case, as it has the .466” base diam required. 7 X 64 is a Euro-spec case that SAAMI maintains specs on, and is a .308 bolt face compatible rimless case.

    I shoot a 6mm calibre iteration of this wildcat, I call “ DEEP 6 “.
    A stock 6.5 X 55 Swedish FL die ( w/ its internals removed ) is used as the case forming die for any & all calibre versions of this wildcat series.
    .224”, 6mm, .25 cal; and 6.5mm variants are all possible, each one obtained by select inside neck ream/outside neck turning; after cases are trimmed to desired length.

    For the .224 cal version, one can rent a .22-6mm chamber reamer, and run IT in “ short “. The stock ( Lee ) 6.5 X 55 FL die I use is comparatively low cost.

    Case loading/ re-loading can be accomplished using 6mm Remington dies, for example.... using a Hornady 6mm Rem bullet seater outfitted w/ a .224” cal seater stem. A wildcat that requires no custom reamers and no custom dies !

    The .224” cal wildcat just described has the same long VLD- friendly neck the .22-6mm case has. This would work out great for use w/ the current heavier .224” LR bullets.

    And while the wildcat’s case oal is just a tad longer than a .243Win
    ( because of the long neck ),bullets can simply be seated a little deeper in that long neck; to keep cartridge oal on par w/ a .243 shooting the same bullet.


    With regards,

    I'd go 22 creed just because forming it in premium brass is so easy. Buy Lapua 6cm and FL size--done!

    Easy button for a modern hot rod 22 in good brass.

    You can neck down 6CM brass but as Hondo64d mentioned, there are places that make/sell 22CM brass and it'll even have the correct headstamp.

    Call me old school but if you want a nice accurate .22cal the tried and true .22-250 never disappoints. If you want to do something a little different, Ackley Improve that bad boy and I am willing to bet you will do everything and more the 22 Creed will and still have the ability to shoot factory ammo out of it. Plenty of brass to choose from and it's easy to find.

    I haven't checked velocity yet. It is supposed to be in the 2500fps range with that load.

    People I know who shoot a 7 twist are about as frustrated as you. I'd think the 80.5 Bergers would have worked- I get 1/2 MOA from them with H4895. The only other decent bullets for accuracy, that I have tried, in the lower weights were the 65 SGK'S. I found a good load of RL-15 26.7 grains. That is supposed to be in the 3000+fps range. The thing is, just a tenth of a grain either way and the groups started opening up. i.e 26.7 gr = 1/3 MOA. 26.6 gr = 1/2 MOA. 26.5 & 26.8 both opened to over 1 MOA. It was a small window!

    I have 2 very nice 223 bolt guns. Both have a .150 freebore for shooting Berger 80 VLD's. 2920fps with 25.0 of Varget and brass life is easily 15+ firings.

    My 223 is on a Borden BRM, Brux 1-7.5 twist in a Wheeler LRB stock. Local UBR match I won "Small Group" with a .236.

    A plain old 223 is just easy.

    Alpha, Peterson, and ADG are all excellent 22 Creedmoor brass. I went with ADG.
