You found H1000!?
I'm looking for it currently for my 7PRC rifle build underway. It recently was available but didn't know I wanted it till it was gone

.
I have some powder to try but I feel that the H1000 is the temp stable variant I want to start working with when performing initial load development.
This will be my new ultralite hunting rig. I have 4 boxes of factory ammo that I will use to sight in the scope and break in the barrel. I still haven't found 7PRC brass yet.
Cheers,
Toby
