Nosler 280AI max loads seem pretty hot to me. Had a rifle that would not handle any of their max loads. My new rifle will but loves 2g below max of RL22 and 140 Ballistic Tips. I have not chronoed but guess is in the 3050-3100 fps range out of a 24" barrel. Nosler 280ai loads are shot out of 26" barrel. I plan to work up some 160-168g loads. Will start with RL22.
