Thread: 280 AI loads

barrel length is very important to get best velocity and benefit from 280AI. I'm running RL22 w 162AMAX in 24in bbl and getting 2850 fps at the accuracy sweet spot (0.3moa). Went up in load dev significantly above that (up to 2950 fps from memory) but groups opened up. 2850 fps gets me to 800 yrds for ethical impact velocities , which is more than I need in most situations.
RL22 is just about as hard to get as RL17 at the moment ... but the new temp stable version RL23 is available in some Sth Is stores. ADI2217 would also be good alternative.
