You will never have a problem with either round in that rifle.
That's what my dad said...Im just trying to understand why he said it? Does that make sense? Sorry I know I am asking a lot of questions but I keep getting conflicting info on the subject. I will be receiving my new rifle hopefully this Saturday and Dad said he is sending 500 5.56Nato rounds also.
I want to take it to the range as soon as I get it but I really want to be sure It will not have a major fubar incident with those rounds.
Thanks again to all that have replied as I will have many more questions soon about my HP C9
