I was using Retumbo and the load was 98.4 grains...last time I used 98 and 99 grains and both showed high pressure signs but this time with 98.4 it showed virtually no pressure signs.
This makes me wonder if I should bump it back up to 99 grains because the cartridge actually shot the best with 99 grains of powder but the presssure signs were definitely there. But with cooler temps and longer OAL the pressure signs went away (at least with the 98.4 grain load).
As you may know, I am just getting into reloading...this is a crazy world! So many variables.
