Good shooting.Once you find the bullet and load it likes.And that may take you some time.It will easily be a sub moa shooter.You’re not far now.

Jimla I have heard that cfe223 is very temp sensitive have you found this to be true with your testing ?

I don't have temp sensitive problems at all in Hawaii, my hunting area and range only changes +/- 10 Degrees year round. CFE223 is know to be temperature sensitive and higher velocities. If you shooting at different temps(cold and hot), I would lose 50-100fps and focus on less sensitive powers like IMR 8208 XBR and AR COMP.

I got a new lot of CFE223 powder, I tried a 10 shot Satterlee's load development and loaded the previous accurate load.

I was surprised how well 10 shot Satterlee's worked, it found my previous 30.8gr and 31.2gr nodes, see graph. At 30.8 it is at a bottom out in a flat area and at 31.2 it is a flat area with a sight drop of Velocity increasing .1 grains.

Nice to see some confirmation of that method.
