This is the email I received Alliant.
" from Looking at the Alliant data we do not have tested load data for this bullet as of yet.
Looking further at the Berger website, they also have not had the opportunity to test this powder.
I am submitting you load request to the engineers for future load data workup. Keep in mind that it takes some time to work up this data. Add to that, getting the Lapua brass to do the testing is also difficult to attain.
Finally, this is a relatively new powder. Data is still being worked on.
Thanks,
Shoot Straight
