    Will have to look at the load when I get home but looking at my Trajectory Chart here my best accuracy and the shot to shot velocity variations were less than 25 fps for 2 different strings averaged 3109 ---- temps were in the 70's both times I shot for record doing development. Will post the powder and charge later---it was either RL 25, 22 or 7828 no that is not a mistake 7828. Both of my AWM’s in 338 Lapua (250gr only) loved that powder so I have quite a bit of it.

    Nice to have 1700lbs of energy at 1k with this little jewell!!
