Your call, I lightly crimp all rounds for my AR, even for my bolt 223, gives consistant burn time on each round and no worry of setback.
All commercial rounds are crimped no exceptions that I have seen.
Since no one knows how hot or light you load, they can not make the call for you. Only you can determine if you should or shouldn't.
Good shooting
Jim
