AS some of you may know I'll soon venture into the dark evil rifle territory and I'm trying to get familiar with the ammo. Its chambered in 5.56 with a 1/12 twist so I've been told to stick to 55 grain or lighter. two days ago snooping around Walmart and comparing 5.56/.223 ammo. Found some 40 grain varmint rounds zipping along at 3700fps but according to Youtube penetration in gel is only 3 inches before they pretty much vaporize. That's not going to be enough for the two legged variety..... [ame]http://www.youtube.com/watch?v=fywBaNSRYGA[/ame] What's your favorite 5.56/.223 and why?
