I've been reloading for 60 some years but new to loading for 5.56 AR15. I usually anneal after each firing of my long range guns (408/338) and others. But not sure about doing that for my 5.56 I don't like to crimp my bullets but was concerned I may not have enough neck tension (usually 0.003" interference fit) after annealing to securely hold the bullet. Any advice or thoughts would be appreciated.
Thoughts on annealing 5.56 ammo for AR15

I anneal after every loading to reduce neck splits and for consistent seating. I don't crimp (either magazine-length or long single-feed 80-grain loads for 600 yards). .003 is about perfect -- I use an RCBS Small Base die.
I lose most cases to neck splits and loose primer pockets. I have thousands of GI cases (mostly Lake City and WCC military Winchester) dating back to the 70s and 80s, but also IMI, Federal FC, Taipei Army Arsenal TAA, and commercial Winchester and Black Hills (Winchester).
I segregate odd headstamps (Fiocchi, Hornady, Norma, Speer, Wolf, etc.) for 55-grain fun "blasting" ammo.

55gr Target Loads.... I clean, load and go. Those cases are avail around here by the 5gl bucket load.
75gr Long Range Loads..... Yes, I anneal after every firing. That brass is kept separate.
