Once more from Wikipedia - the link in Post #3:
Winchester is currently offering five different loads for the new cartridge: a 150 gr (9.7 g) Deer Season XP at 2,350 ft/s (720 m/s), a 180 gr (12 g) Power-Point at 2,100 ft/s (640 m/s), a 160 gr (10 g) Power Max Bonded at 2,225 ft/s (678 m/s), a very affordable[citation needed] 145 gr (9.4 g) FMJ in the USA ammo line at 2,350 ft/s (720 m/s), and a Super Suppressed 265 gr (17.2 g) subsonic load at 1,060 ft/s (320 m/s).
The cartridge offers a flatter trajectory with less recoil and better terminal performance over current straight-wall cartridges, while remaining compliant in most applicable states. With the same barrel length, .350 Legend generates more muzzle energy than 30-30 Winchester and 300 Blackout.[citation needed]
