There is a lot of good info on here about the 280AI and load/bullet data. I didn’t find a lot about twist rates and bullets. I’m looking at getting a rifle chambered in this round and would like opinions on barrel twist. I would like to use a little heavier bullets like the 162 ELD X or heavier and possibly the 175’s. Would the 1:9 twist be good or should I look at something faster? It will occasionally be used on elk out to 500 yds and mostly on whitetail, 6-700 yds. Thanks in advance for the input.
