So, Is it the bullet then, that determines the OAL rather than the powder charge?
I am working up some test loads for my G17 with Silhouette, 231, and Universal. I WAS going to vary the OAL using 1.10,1.12, and 1.15. Should everything be 1.10 with the MG 124 JHP? BTW, the OAL of the factory 115's in Fed or Blazer is 1.152.
