I full-length resize all new cases, whether I purchased R-P, Winchester or Federals. After resizing, I measure them with a caliper, and if any are quite a bit longer than the average, I trim them. I prefer all my cases to be the same length at the start, so they remain relatively uniform over the life of the case. I then chamfer and deburr all the cases. Again, uniformity. Now, I only handload for rifles, and hunting loads at that, so I normally do not load more than forty cartridges at a sitting, so this process is not that tedious. If I was reloading varmint or pistol/revolver cartridges in batches of hundreds, I might feel differently.
Although all the new cases I have purchased (.30-06, 7mm Rem Mag, .30-30 Win, .338 Win Mag) have been well-manufactured, they do get a little beat up during shipping and handling. Case dents, as long as they are small, do not concern me. Out-of-round necks do, which is why full-length resizing new cases makes sense to me. You are not going to rework the case much, since they come "full-length" from the factory. You are merely trueing them up before priming, charging with powder and seating a bullet.

Midway states in their catalog to full lenght resize, trim, and chamfer before using new brass. In the rifle section not sure about pistol .... I usually check and see if it will hold the bullet and if it's the right lenght (pistol)

I have always had a few cases with dented case mouths so I always run them thru the fl die if for nothing more than to maintain consistency. If one is dinged and will be run thru the die I will run all of them thru the die and then chamfer. Never have had to use lube, account cases are all ready to spec.

I too always FL resize new brass. For the aforementioned reasons of caved in mouths, etc. The last 2 batches of 35 Whelen RP brass i've gotten have been pretty terrible.. no way you could even begin to seat a bullet in many of them.
on new brass, after i FL resize i also trim, chamfer the mouth, true the flashhole, chamfer it and true the primer pocket... this is the only time i do all of this. From this point on i neck size only and i'll check to see if the mouth is still square after fireforming. other than that it's just check from time to time to see if they've stretched too far and need trimming again.
Reason i do the primer pocket is from the fact that what i thought was excessive pressure turned out to be a primer pocket situation where they were not formed deep enough... the primer was actually flush to slightly protruding above the rim face.
i've also noticed with the 35 WHelen brass a significant amount of runout and perpendicularity... meaning the neck is not true to the C/L of the case and the rim face is not square to the C/L of the case... some are so bad that you can't even get the case trimmer pilot in the mouth...
Fireformed with a good load and they are about as true as you can get them eventhough they "suck" out of the bag...
On another note the 280 rem nickel brass i shoot is pretty danged peachy right out of the bag...
