Hey, first time AR owner here... Just put it together : CMMG 16" M4 carbine 1:7 upper with CMMG lower and magpul CTR. So my problem is, I'm getting a little confused on the ammo selection. My rifle is chambered in 5.56 but I also know that it'll accept and fire .223. I understand the pressure differences and the small deminsional size differences but my questions are: 1. How much accuracy or muzzle velocity do you loose from using .223 in a 5.56 barrel? 2. Is .223 acceptable for plinking and training in the above set up? 3. As far as grains go, I've read that a 1:7 will handle the heavier rounds -- but 55gr will be fine? From what I've read it's more of a 'see what works best in your rifle' type situation, but I'm really interested in what you guys are using for training and self defense purposes! Alot easy to find .223 in my area as opposed to constantly ordering 5.56 Thanks! |

I shoot both in my Armalites,DPMS and S&W rifles all of which are 5.6 and 1.9 twist barrels and do not notice a discernible difference.The .223 is supposed to have a bit more freebore and lower velocity.Buy it cheap (If You Can) and shoot .223,do not think rock,paper ,cans and the like will ever notice. Many folks here get all caught up in the techy stuff and that is good and occupies their interest but seem to forget that having fun actual shooting is good also and why we have them |

Man I love it. Alot, of folks come with their new rifles and are confused about what to do NEXT. Yes, I understand that folks want the best and don't want to make an expensive mistake. Yet, they buy a rifle w/o much of a problem while spouting off the sexy lingo. (One of my "pet peeves" being........calling a 16" barrel Carbine, an M4.) But, whatever.......maybe, it's me. Maybe, I'm the "snob.'' I need sensitivity training. So FWIW, IF you've already read it......I apologize. IF you haven't........I hope something will stick. ammo.ar15.com/ ________________________________________________________ Things come at a "cost." What your budget will allow, is a large factor to consider when deciding. A lot of folks like to spend other people's money........BEWARE. Set your own budget for this ammo purchase project. IMHO.......having the expensive ammo........but, not getting to practice with it, is fool hardy. Aloha, Mark |
