AA pellets have always been made by JSB, they financed the whole thing as prior to AA's involvement JSB only made match type pellets. That was the reason JSB's could not officially be imported into the UK.
In the end AA realised they were fighting a losing battle and they are now the official importer of JSB pellets.
All of that said, I agree with the above, I have more than ten different batches of JSB's and the difference between some batches is huge, they do not even look like the same pellets.
