123gr A-MAX factory load surprised me at 1200yds from a 16" Grendel, but I'm at higher elevation-4400ft that day. That ammunition is supersonic for me out to 1318yds if I believe the G1 drag model, and it actually worked out for me at 1200yds for some reason. I had accurate temperature and baro pressure readings I guess.
