This has been a very good thread and has received great contributions from some of our very knowledgeable members. I just received a couple of boxes of 150 gr .284 BD2's for a 280AI 8 twist 24". I was hoping to get 3000 fps with some of my available powders. I'm not going to fret over +/- 50fps, but need to start my first loads to see results. As I mentioned in another thread I was thinking about trying RL23 with either BR2's or Fed215M in Peterson brass. Other powder options include H4831sc, H4350, H1000, as well as many IMR powders. Thoughts here would be appreciated.
