If you look at underwoods ammo ? Their ammo is the full recipe so to speak. Pricing not bad and I think you can get some of their load data.

Answered here, at least concerning the original Norma loadings, starting years ago:

IIRC, the FBI never actually issued the "full power" Norma 10mm loading as it was deemed to produce excessive recoil during the testing phase. Agents were issued the reduced-power Federal loading from the get-go which, depending on the source, delivered a 180-190gr bullet at 950-1050fps. Federal's current 10mm Hydra-Shok offering is about the closest to the "FBI load" in terms of ballistics that is still available, but the original used the older JHP design which I believe Federal now calls the "Hi-Shok".

The FBI initially issued the full loadings, but agents were not receptive to it in general. It scared them, and many had a problem qualifying with it. THAT is when it got watered down. It just overwhelmed enough of them, who complained, and the compromise was born.

I don't think the FBI ever issued the full-power loads. Testing revealed that they could get the performance they wanted without 10mm ballistics, so they - the training unit that was evaluating guns and cartridges - developed a new, reduced load for FBI use. The "gun's too big", "too heavy", etc., mostly came into play later, when the FBI wanted to justify getting out of the 10mm.
