338 Lapua AI

[ZWA]

Hello all,
I have a new build I am currently working on load dev for and thought I would share since this round/data seems uncommon. I have found information on various sites with the 300gr Berger EH but the data on a 250gr EH is slim to none. Appreciate any feedback on this and hope it helps others.

Built by the great team @ WTO
JGS Reamer print #97420
Lone Peak Fuzion 338 action with Alpine cut and WTO switch lug
24'' Bartlein in Heavy Palma 1 in 9.3 twist with 5/8'' threads and WTO brake
Foundation Exodus stock w/ Hawkins hunter DBM and mag

For fireforming I ran all 50 pieces of new Peterson Brass with load below
CCI 250
Sierra 250gr SMK
80gr of RL22 (yes this was pretty dirty powder)
Avg 2607fps across all 50

First round of load dev with no pressure signs and recorded on Garmin Xero
Ran brass through Redding 338 Lapua 40* full length die set #80927 with a 2thou bump
CCI 250
Berger 250gr EH
90.0 - 94.5gr of H1000 in half grain increments
90 - 2637
90.5 - 2654
91 - 2712

92.5 - 2685
93 - 2747
93.5 - 2768
94 - 2777

Next 10 rounds will be 95.0 - 99.5 with H1000 in the same configuration.
