EXACTO technology is claimed to markedly extend the day and night-time range of current sniper systems. [ 4 ] [ 5 ] How the ammunition is designed to change direction in mid-air is classified. The second phase of the program was completed in summer 2014 with a number of improvements provided.
According to Browning, the .223 WSSM offers a 600 ft/s (180 m/s) gain with a 55 gr (3.6 g) bullet over the standard .223 Rem. It also offers a 440 ft/s (130 m/s) gain over the .22-250, a popular varmint round. This comes out to a 600 ft⋅lbf (810 J) gain over a standard .223 Rem, and a 350 ft⋅lbf (470 J) gain over the .22-250. [9]

Maximum range is constrained by use of the existing Hydra 70 motor, but since the seeker can see as far as 14 km (8.7 mi), a more powerful motor could extend range while retaining accuracy. [11] Nammo is working on a modified rocket motor that can extend range to 12–15 km (7.5–9.3 mi).
Early production rifles had a 1:12 twist rate and post-2014 rifles have the 1:9 twist rate. [3] The CZ 527 Varmint in .223 has muzzle velocities for standard-load 45-grain (2.9 g) ammunition of around 3,500 feet per second (1,100 m/s). The 1:9 barrel twist in the Varmint Kevlar reduces muzzle velocities by about 1.5%.
