What .30 or larger caliber most closely matches trajectory of 855? Interesting question: While not quite the same..I note on Page 117 of book: 'The Ultimate Sniper' by Major John L. Plaster USAR (Ret) That Federal 0.223 Match and Federal 0.308 Match have approximately the same bullet trajectory for a 100 yard zero and approximately the same bullet velocity at about 1000 yards. Muzzle velocities are very different though with the 0.223 being approximately 400 fps faster. At about 400 yards they velocities are almost equal. at: 1000 yards the 0.308 round is moving 100 fps faster. The wind drift of the 0.308 bullets is significantly less at 1000 yards than the 0.223 round |
