Here are some chronograph results which have been posted on the forum. The Hornady 123 ELD-M and SST need a minimum velocity of 1800 FPS to expand. I haven’t seen any chronograph results on 90 grain Federal TNT out of a 12” barrel.
12” PSA SS with LabRadar.
123gr Hornady American Gunner bulk HPBT = 2201 FPS ave with SD of 14.7 (2" to 2.55" groups)
123gr Hornady ELD-M Black = 2265 FPS ave with SD of 13.2 (1.4 to 1.7" groups)
123gr Hornady Custom SST Factory= 2277 ave with SD of 11.8 (2.9 to 3.2" groups)

Wolf steel case at 2364 Avg. SD was 9.7.
