I have the Nosler reloading manual 7th ed.
I load for the AR-15 also, Nowhere in that manual does it state "Crimp" this bullet. Unless you have a full auto M-16 don't.
By crimping this bullet in this instance you will deflect metal because it has no indentation area on this bullet.
Overkill for this application in my Opinion. It also increases pressure!
