Glad you got things to work, and I see you ended up with a fairly conventional powder and a proper crimp diameter.
In the long run you might want another tenth of a grain of powder just to make sure in all weather you exceed power factor.
Clean gun every match and practice session - it's the key to keeping a good load and a good gun running.
The OAL that works for a bullet design is highly dependent upon the nose shape. For example, my 200 grain truncated cone nose loads feed perfectly at 1.180" OAL.
Nothing beats testing - except practice and shooting matches. So, sounds like you are ready to do both!! good luck, GJ
