Went through a lot of bullet/powder combos but finally got a load with the 115 NP between 1/2-3/4 groups with imr4831
Even though your's is an AI and my custom is a standard Bob, it too is finicky. like yours it like the 115 NP/PT....IMR 4831 combo. it was the first combination i was finally able to get to shoot in this rifle.
