A few years ago I was talking with a guy that said most .223 bullets under like 62 grain werent good for shooting out of AR's cause of the faster twist rates. He said the lighter bullets would just spin apart as they flew through the air... What is your experience with this? Im asking cause I have quite a few of these rounds around for my bolt .223 and am getting them 11 cents cheaper a round than say FED bulk stuff thats 62 grain... Im gonna go shoot 500 rounds next weekend at paper with my AR out to 200 yards. I dont care about match grade accuracy but I want my shots to get to the target without vaporizing... I get good results from these rounds with my bolt gun out to 200 yards but its 1 in 12" ... Thanks for reading!!!
