I think I'm being too tough on this gun and expecting better results!?!
Thanks JD,JD338":3p66j10l said:RL22 is my go to powder in the 280AI for 140-160 gr bullets.
With the 160 gr AB, 60.0 grs RL22 went .092" and 3000 fps.

That bullet is a Flat Base and at the seating depth I'm using sits right below the neck in the case, and why I had to use so much powder to achieve that velocity. I'm going to back it off by a grain though 'cause I don't like to run them that hard.
JD what twist are you using? And what is the proper twist for the 160 AB and LRAB?
