    Hi Team,

    Thanks for all the advice. Going with a fast twist 22-250 AI Tikka in a GRS Berserk stock.

    Will throat it for the 75Amax and get a 20MOA rail, Gunworks maximus, glass bed action, AI mag bottom metal, Tikka Snow bolt knob (off super varmint) Spuhr mount, S&B 5-25x56 Mil / Mil DT for glass.

    Will put pics up when complete

    Bog standard 223?

    My remington has gotta be up over 6k rounds through the barrel by now.. Maybe 60/40 varied factory ammo vs warmish handloads.. Have started to wonder recently if it was starting to open up a little bit, but maybe I've just forgotten how to shoot paper. Rabbits and roos still die fine.

    I believe 6-10k rounds is about the expected life of a 223..

    Will the 22-250 feed through the AI mag? I have a T3 in 22-250 and was liking for extra mag capacity but every extended mag option I came across has an express disclaimer on the feeding of 22.250?? Ended up importing 4 extra factory mags out of the USA.

    The biggest killer of barrels outside of erosion is heat. Keep your barrel cool and you will extend its life considerably.

    22-250 with AI mags 22-250 AI has very little taper adn therefore should work from a 10 shot mag, but in my experience the only way to find things out for certain is to do em yourself, besides its just money...

    @StrikerNZ my good friend is a rabbiter in central uses 223 55gr V-Max, 24.5gr WW748 and got 15k out of his last barrel before he started to shoot below 95%. Then he re-barreled, accuracy went from .5 to 1.5 MOA and missing too many.

    When you do it for a living, each shot counts and each miss costs.

    Load development this week coming before the maiden trip to central.

    Went with a 22 Terminator (22-204 Ruger) via @Kiwi Greg and Tom Curtis at Deadeye Dicks

    Dies sorted and 600 x 75 amax arrived, also have 300 x 50 z-max too.

    I will try 222 Rem Mag data and work up with WW747 (belmont action rifle).

    Should get 22-250 performance without the noise, recoil for less than 30 gr powder.

    Glad you asked.

    Just got back and managed to knock over a fallow yearling at 350m, 10 Wallabys at around 300m some goats in the nevis out to 400m and i didn't count the rabbits.

    Load dev was good.

    I tried the 75 gr Amax and 50 gr Zmax all with Murom SRM primers and Belmont Action Rifle powder.

    50 gr Zmax still require more load dev as the 29 gr loads showed no pressure signs but I didn't manage to chrony them. The 27 gr load was doing 3250 but i should be able to get plenty more.

    Still waiting on some load data from KG for 2206h and 2208.

    Settled for the 75 gr amax doing 2880 fps and thats what I took all of the game with.

    Terminal performance of the 75gr A-max was superb on the Fallow, low chest shot took off the bottom of the heart and lungs, exit was about 2" in diameter, observed the claret pumping out at a furious rate before she collapsed. The gun is so quiet you don't require hearing protection and soft shooting you can observe fall of shot.

    Tried to film the deer but was on last light. Here is the first of the wallabies shot (onside shoulder and exit in neck), next nine were at ranges between 250m and 2m, again great terminal performance.



    Those wee pills are great at bucking the wind



    Big thanks to @Kiwi Greg

    How big are the squares?
    A hornady tech told me 50gr v or z max will self destruct on the way to the target in a 8 twist at 3300.
