I need input from 338 edge users.
I used my old trusted load for my edge 93.5gr H1000 with 250CCI M Primers on rem cases behind a 300SMK bullet for long time.
Speed of the load is 2870fps for more then 2 years with 0.5MOA group.
I get the primers, powder, cases at bulk quantity to last for 2 years.
Recently I run out of H1000 old powder and I got another 16lb few week ago.
So I reload my old load (please note the load was mild, 96g of H1000 was neat hot load) so 93.5g with new powder batch #4826 supposed to be ok.
I reload 10 rounds and headed to range to verified the pressure and group
at 200yrds I got the following group
So, I aimed at 780yrds and took 2 shoots. I was hitting very high.
Did trajectory validation on Exball and from 2870fps I jump at 3042fps speed.
I could not believed. No pressure signs, no marks on head case.
With new trajectory validation and new speed on Exbal I aimed at 1200yrds and i got hit after hit on metal plate.
I'm very surprised to get 3042fps on 338edge (rock 30in barrel)
Did somebody else encounter the same problem with the new batch of H1000 powder?
I have to head back shooting next week with the same load to make sure will hold the speed and group.
