. Since my barrel has a 1/9th rifling twist, several people told me that the SD rounds I have are too heavy for my barrel to stabilize and thus shoot accurately. But since this rifle will be mostly for SD and CQB purposes, I realize that any ammo will do the job. I guess the only thing I need to be concerned about is choosing the best ammo for plinking and long-distance target shooting. According to quite a few opinions, .223/62 seems the most ideal for target/distance shooting for the kind of rifle I have. What do you guys think? I appreciate any input since I am still new to the AR platform.
Yes and no. I have a 1/9 Colt along with a 1/7 Colt. The ammo best suited for 1/9 is under 70 gr but that doesn't mean that heavier doesn't work. People tend to repeat stuff but never try it or even look up what is ment but "not stabilizing". The ammo will work just fine it just won't get you little tiny groups everyone tries for. It's still perfectly capable of center mass shots.
For range use I buy whatever is in 223/556. Most common is M193 or XM193 (same thing) which is 55gr. That ammo will work just fine unless you're trying to go past 500 yards and or on a windy day. Stock up on 55gr and try others as well ....nothing wrong with that
