Not sure of exactly what “warp speed” is, but have had extremely good success (dating back to the original X bullet of the early ‘90’s) with TSX’s with a muzzle velocity of 2900 FPS. Mine in particular had low BC’s.....but somehow managed to kill very effectively to 400 yards and a bit beyond! memtb
Did not have reliable success with the original 'X' bullet and could never bring myself to use the TSX as a result. The MRX, TTSX and LRX have been 100% reliable on coyotes, antelope, mule deer and elk using .257 Roberts, 6.5CM, 7mm RM, multiple .30-06, .300WM. Not one recovered so far, right around 50% straight down DRT with no animal going more than a few yards. My hunt group has used handloads and factory ammo and we like them. A lot.
