I just ordered 2 50 rd packs of THIS:
http://www.precisionriflesupply.com/...ed556-55gr.htm



Anyone try this? How does it run? Is it reloaded military brass? I am not sure what the rifling twist is in my 20 inch hbar classic, so I am unsure what grain to use. Depending on the rifling twist, what grain SHOULD I use? What does 55 grain work best in? What does 62 grain?


Also, is this stuff any good?
