Looking for some input which do you all prefer? Any pros and cons? going to purchase a 1000 rounds of one or the other. I have been shooting the LC Federal 5.56 62 grain m855 and like it. Groups very well and will run with out a misfeed or jam. However I can buy the remmington .223 55 grain for a lot less per 1000. I have not shot anyb of the remmington ammo. Let em know what you all think
