Q: I was inspecting these rounds and it appears the tips have been dipped in a green paint / substance. Is this to help track the firing trajectory, or a simple manufacturing design. Thanks.

A: These are called "Green Tip" 5.56 rounds. This paint on the nose of the bullet is to help distinguish standard M855 ammo (green tip) from M856 tracer ammo (orange tip), M995 AP ammo (black tip), and Optimized (for short barrels) ammo (brown tip), among others.
Q: Does the product box list stats like ballistic coefficient, expansion, velocity etc. or do I need to find a website with that kind of information for each product? Can you recommend a reliable website that has accurate information? Im trying to find rounds that will work well in a survival situation for hunting larger game like white tail deer.
Thank you.

A: Rob,
the G7 ballistic coefficient (BC) of the SS109 projectile in this M855 ammunition is .158. Please note that a G7 BC is different than the G1 BC provided by most manufacturers, but it allows for a more accurate calculation of trajectory and wind drift.
The velocity of this ammunition is 3,100 feet per second from a 20" AR-15 or M16A2. It is not expanding ammunition, rather, it was designed to meet specific armor penetration requirements at various distances.
A better choice for light, thin-skinned game such as white tail deer would be the Federal Fusion 62gr bonded ammunition.
Q: Would you recommend this ammo for personal defense? If not, which would you recommend?

A: What are you defending against? This M855 ammunition was designed to defeat steel armor at extended ranges. From an M16A2, it will penetrate a 10 gauge sheet of steel as far as 700 meters from the muzzle! Against soft targets, 75gr or 77gr HPBT and 62gr bonded ammunition such as Federal Fusion are much better choices.
