    Question ADI 2225 anemic compared to old batch ?

    Hey guys and gals,
    So I was lucky enough to score a couple tubs of the latest shipment of ADI 2225
    My old batch I was loading this for my 270wsm
    Specs as follows:
    Hornandy 145gn eldx projectiles
    Norma brass
    CCI LRM primers
    Charge weight of 71.5gn
    which was certainly hot but fine in my rifle and gave average velocity of 3153 fps with an e.s of less than 10fps

    With my new batch whilst still getting great accuracy and no pressure signs even with a well compressed load I am getting nowhere near the velocity I got with the old batch.

    Loaded up a ladder today, the only difference being I am now using federal large rifle magnum primers as cci is unobtainable.

    69.5gn: 2992, 2998, 2977 fps

    70gn: 3015, 3021, 3010 fps

    70.5gn: 3037, 3011, 3040 fps

    71gn: 3052, 3013, 3058 fps

    71.5gn: 3079, 3066, 3050 fps

    My old batch

    69.5gn: 3098, 3115 fps

    70gn: 3116, 3095 fps

    70.5gn: 3118, 3136 fps

    71gn: 3139, 3158 fps

    71.5gn: 3152, 3153, 3151, 3156 fps

    It seems to me the new batch is quite a bit slower velocity wise for the same charge weight and with the new powder my best e.s seems to be at 70gn at a avg velocity of 3015fps accuracy was good throught out the charge ladder with all but the lowest charge weight shooting sub MOA.
    Now I know that lower velocity will be kinder on hard to replace brass and I am also conflicted because on one hand having a 270wsm I kinda like the idea of having it shoot super flat at higher velocity than a 270win but on the other hand the 270wsm can also do everything a 270win can but in a short action....

    Has anyone else found the new shipment of ADI 2225 powder to be substantially slower ?

    Yes I know that a 145gn eldx pill doing 3015fps will kill deers out to plenty far enough, it just annoys me that I can't even match the claimed velocity on the box of the factory eldx rounds of 3100fps.
    There is definitely no more room in the WSM case to put anymore powder in them as it is very compressed at 71.5gn in my max seating depth.

    Anyone got any wisdom to chime in with ?

    im like 300-400FPS slower than the box speed with my full lenght barrel tikka t3(previously 7mm08) with the Precision hunter 280rem

    the barrel on the test gun must be loose as a goose and 35+inches long

    take the box figures with a grain of salt

    You deffinately get different results from different batches of powder.
    I had a load using 71.5 grns had to drop to 69.5 grans with new batch which was a couple of years ago because the new batch had way more grunt.

    Oh definitely, just wish the velocity was up there with the old batch.

    Not yet, and before anyone points it out I know optical chrono's are consistent but not accurate but it should still be within 20fps and all rounds shot today were in same conditions and 5 minutes minimum between shots to allow the barrel to cool.
    I think I'm gonna load 3 more at 70gn and run them over a labradar for verification at this stage.

    I did try ADI 2217 and was getting marginally better velocity but was getting heavy bolt lift and worse e.s

    Hey @dannyb maybe you should have posted those 2 containers of AR2225 on the thread - things I really hate

    Either way I don't hate them, just curious more than anything if anyone else has found the new batch to be slower

    Chronograph mate... unless you had some rounds left from the old batch and you fired them on the same day as the new batch?

    Has the outside temperature been similar on both occasions of velocity testing? Im not sure if 2225 is temp sensitive, but just a thought, especially if your recent testing was a cold day.

    My 22" 270wsm with Federal and Winchester brass, Fed mag primers and 69.5 old batch 2225 and ELDX is 3140fps. So I doubt if its the change of primers that have made the difference to yours.

    What did you think of the new 'scope?

    Open one of the other new containers of 2225 if they all have the same batch number an see if results as the same. I have had the same thing happen with 2217 but gained a 100fps instead. One trick i herd of is to use half a tub an then mix with a new half tub as it reduces any difference by half.
