Thanks guys for the info, but I'm starting to think my barrel is going downhill. I have tried everything I can, and I still am getting inconsistant groups. I have found 33.4 grains to work the best, but one group will almost be touching, and the next group will be over an inch, not much over an inch though. I have gave up trying to figure it out, I have also tried new brass against my older brass, and there is no difference.
I have also tried different seating depths, all kinds of different charges, different graqin bullets, and its all the same. Just when I find a group that I am happy with, the next group of the same combination will be a lot more open.
Thanks for the info!
