So spent a lot of time at the range today. Between reloading trips and back and forth to shooting almost 6 hours. It was a good day. I have been developing a load for my 280ai with the174 EH. Pushing them to about 3020. Couldn't get them to group for nothing. Loaded up some 180s now this is where it gets interesting. My 280ai is pushing the Berger 180Hvld at 3010 FPS with 60.7 grains of reloder 26. In little tiny groups. I don't know if it's the fastest 280ai but wow.
