I am reloading .223 for a M4. I am using Remington 55gr FMJ w/ cannular, I am finding a variation in bullet length from .712 to .738. The common size that has the most in the length is .724 at 20, all the rest are at 2 to 9 bullets out of 100 count. Has anyone run into this problem? I am thinking of setting up my seating die using the .724 size to try and get a consistant OAL. Any suggestions are welcome.
