Very little load development attempted.......it shows great promise.
100 yard target?
What is a 150AB?
Yes, 100 yard 3-shot groups are what I do when trying to find the best load. Never did mess with seating depth on this load but I am sure you can dial it in some by doing that. Too many guns and not enough time to fool with them anymore. "150AB" is 150 grain Nosler Accubonds.
