Does anyone know the expansion velocity thresholds for Hornady 55 gr TAP, 75 grain tap, and 64 grain speer GD loads in .223/5.56? thanks...

55gr TAP is a VMAX bullet, unless you are talking about the TAP GMX, in which case that is listed as 2000fps, the 64gr GD is still performing down to around 15-1600fps, and I don't recall what the VMAX minimum expansion/fragmentation velocity is. Something in the mid teens, I would guess.
big game sp's, spitzer style, about 1800 fps, varmint bullets still frag at much lower speeds, maybe 1400. I'd never trust them for defensive use, tho. I"ve seen them just blow 1" wide and 2" deep "craters" in coyotes. That was 3000 fps, very close range (at night, electronic call) and 50 gr hornady SX, which are so fragile that they don't exit a chuck.
