Who (re)sizes brand new brass before using?

In comparing notes while at the range with another shooter (he is a full on "benchrest" type), I told him I had some new brass on order, and I was going to chamfer the case mouths, prime them and load them up. This brought a howl from him...

It seems I've been doing it wrong the last 40 years.
According to him I need to:
1) Weight sort them (+/- 1 grain)
2) Neck size them
3) Trim to length
4) Chamfer case mouths
5) Load...

This is new Federal brand brass that is intended for high volume ground squirrel control. It will be shot out of multiply factory bolt action rifles.

Anyone else use this routine with new brass? I certainly do all that with fired brass. Maybe I should just buy once fired
and save the extra cash over factory fresh...
