Just saw a tv show that had one section on long rang shooting.
The weapon was a Stock Sig 5.56 MCX with a 16" barrel and scope.
The ammo was Hornady's new 73gr. ELD match bullet with a
BC of .133.
Muzzel vel of 2790fps at 3,000 elevation and temperature at 65 degrees. **
Metal target looked like is was about 12x16", painted white.
Test range was at..................... 1270 yards.... -9 degrees.
Scope was adjusted up by 78.6 MIL.
First two shots missed.........
next four in a row , hit the target.
Not bad for a .223 round, for only target and gong shooting.
They stated that the bullets energy at that range was 122 ft/lbs.
Weapons and ammo has come a long way.
** MV 1270 correction to 2790 (Midway ammo)
