Most of our AR 15's have a 16" barrel with 1/7 twist rate.
The most Popular bullet is a 55 grain FMJ bullet. Information I read states a heavier bullet is needed.
Heavier 223/556 bullets are harder to find.. Plenty of 55 grain bullets are available. Why is the 55 grain so popular? Are there that many bolt action 223 rifles out there with a faster twist rate?
I may be be completely wrong or confused about the whole thing. Let me know!
