A lot of people ask what exactly does steel core mean in a round well here is some info, these are some videos i found online that can help show the damage done by these light armor piecing rounds.
This is a Nato round and is used in our military.
Cartridge, Caliber 5.56 mm, Ball, M855 (United States): 5.56x45mm 62-grain FN SS109 ball cartridge, green tip w/steel penetrator and a lead core.
Now how much damage does this round really do???

Also just to let everyone know there is a new m855 out callled the M855A1
M855A1
M855A1 Enhanced Performance Round and its environmentally friendly projectile.
June 2010, the United States Army announced it began shipping its new 5.56mm cartridge, the M855A1 Enhanced Performance Round, to active combat zones. During testing, the M855A1 performed better than current 7.62x51mm NATO ball ammunition against certain types of targets (particularly hardened steel), blurring the performance differences that previously separated the two cartridges. The US Army Picatinny Arsenal stated that the new M855A1 offers improved hard target capability, more consistent performance at all distances, enhanced dependability, improved accuracy, reduced muzzle flash, and higher velocity compared to the M855 round. Further the Army stated the new M855A1 ammunition is tailored for use in M4 carbines but should also give enhanced performance in M16 rifles and M249 light machine guns. The new 62-grain (4 g) projectile or bullet used in the M855A1 round has a copper core with a 19-grain (1.2 g) steel “stacked-cone” penetrating tip. The M855A1 cartridge is sometimes referred to as "green ammo" because it fires a lead free projectile.
The M855A1 was put on hold in August 2009 due to the experimental bismuth-tin alloy core exhibiting undependable ballistics at high temperatures. The US Army has since replaced the bismuth-tin alloy core with one of solid copper eliminating the heat issue. The United States Marine Corps purchased 1.8 million rounds in 2010, with plans to adopt the round to replace the interim MK318 SOST rounds used in Afghanistan when the M855A1 project was delayed.
