I think I'll wait and see some non paid reviews before looking at another new powder.

agreed

In my opinion this is just a repackaged "extreme" powder from Hodgdon

The info straight from the Hodgdon ballistician is these are new "green" powders that are temperature insensitive. Not repackaged Hodgdon powders.

I really do not need to try any new powders so will wait and see if these pan out.

Has anyone seen a burn rate chart with the new propellants listed?

Not sure if they're listed but you'd think Hodgdon would update their own chart: https://www.hodgdon.com/burn-rate.html

Powder Valley says close to Varget but it is a wait and see thing.
