  1. 5.56 comes in multiple weights, from 55 grain, 62 grain, and 77 grain. The major advantage of 5.45 is relatively light (53 grain), high velocity (2950), with a relatively high BC (G7 .168). It does very well in the wind and has really good penetration in most situations. It's light, so you can carry a lot of it.
