Thread: 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 ?
