I was playing around with a bunch of different light loads for my wife trying to reach the bottom end of major. I didn't get close with my first attempt, but I thought I'd post the velocity difference with the same powder charge and two different seating depths.
Load was 4.8 grains of W231 using a cast Lee tumble lube 200 grain SWC.
OAL = 1.250" = 686 FPS
OAL = 1.200" = 734 FPS
Obviously there was a pressure increase to match the added velocity.
Just food for thought...
