55 gr. versus 62 gr. .223 !?

[InFlamez]

Hey all,
What are the the results and advantages/disadvantages between 55 grain and 62 grain .223 rounds ??? I know there's been multiple U.S. military investigations and reports on these different weights, but does anyone have a simplified explanation or links to some comparisons? ....Just curious while planning a bulk purchase. Thanks.

Many ranges will not let you use 62 grain M855, due to fire hazard concerns.

The ammo oracle is the best place (or a simple search on google.com) but for me it's: one fragments and one penetrates.
