Your link isn't working. From what I've gathered reading posts over the years MOST benchresters are FL sizing. But, they are using dies that are custom made to match their chambers. Seems most of them want to make sure there is not going to be a problem with any tension while closing the bolt and therefore they are bumping the shoulder ever so slightly every time. The way that I gather it the dies are made to barely resize the brass (except for the shoulder bump)and they don't even use an expander ball.
Here is another great link.....you'll see all kinds of different ways to prep brass from well known experts. Some guys don't do much....others are so sanitary about reloading that they wear latex gloves!!
Don't know if you read it or not but the latest Shooting Times Magazine has a really surprising article on a factory Savage rifle made for match shooting. This rifle shot 7 different loads to under 2" at 500 yds. Factory ammo shot every bit as good (and on average maybe better) than handloads. Kind of made me believe that a good...no great.....gun isn't going to be that fussy about whether you neck size, FL size, Collet size, body die, or care about runnout.
