Related but also not really related question. I shoot my wylde chamber AR at distance. I pick up my own brass and I'm planning to start reloading soon. Since it is all "my" spent brass and I don't dump magazines through the rifle can I get away with neck sizing?

I imagine if I just neck size like a bolt rifle and keep my OAL under the max I shouldn't have too many problems since the brass is from my chamber. Am I way off here?
