going to try to get some bench time today got some more ladder loads ready to test. bumping up in .2 grain increments from here. still had a little case sooting at 37.6 looking to seal it up and keep good accuracy. think i may be getting close. these loads are for my rifle start low and work up looking for pressure signs. good luck good shooting. more to come.

Are you chronographing the loads? Curious about velocities with the 260 grain.

If I'm not mistaken the BCA upper is a 1/24" twist rate correct? I'm curious how these will perform in my 1/20" twist... I just need to find a new place to try them out. I've got a bunch loaded up with H110 from 37 grains up to 40 grains.

Here's a four shot group I shot today at twenty five yards. I couldn't go further because the rest of the range was occupied so I just adjusted things to be six inches high. The load used was new Starline brass, Winchester primers, and 39.5 grains of H110.
