The bullets are not the issue. I am the other person that a matt is talking about.
My bullets work GREAT in my gun and I use AutoComp at around 181-185PF. I have tried his bullets in my gun and they are not accurate at all. But, his bullets in his gun work GREAT and he gets nice tight groups with it. And I have given him my bullets to shoot out of his gun and they are all over the place. He has tried a bunch of different powders and they are all, all over the place.
Now....has anyone else ever experienced this before???
