US Marine Corps, Camp Perry 2006

i love working for the NRA. i get a tone of hours and get to meet a lot of cool people. can't wait till this June to go back to work and set up the pistol range. i will be my third year in 09.

Yep 600 yars and iron sight... they do it at 1000... and iron sights and a 223. or realy a 5.56 yes their is a differance.

The Shot groups by any shooter at the 300 rapid shout allways be cleained. Or a possible as we called them.

If you can not shoot a Possible at the 300 and soo with onley a 2 point drop at each one of the other yard lines then you wont wine.

Most of the shooting is a match is done from 200yd's to 1000yd's Iron sight.

.223 is the english measurement. 5.56x45 is the metric measurement. Its the same bullet, though.

not really military has changed the seating depth and bullet contour and increased pressure of load,so that rifles firing 556 require a longer leade cut in the chamber for safety.

the base rounds are identical, its the same difference as celsuis or degrees. they both say the same thing, just different ways

thats why ammo boxes (for civilians) say 5.56x45 and below it .223

toddm-SAAMI issued a warning in 1979 that military chambers are cut differently,and that military ball may result in high pressure in sporting rifles.I use military surplus in my mini 14 all the time with no problem,but the warnings are out there,and there may be a rifle with very tight chamber demensions that would have a problem.

thats probably what it is. all im saying is that my boxes of ammo, remmington .223 55 grain FMJs, have .223 and 5.56 on the box.
