I'm referring to short, medium and long range competition. Benchrest, F-Class or High Power rifle. High Power folks' been full length sizing (without expander balls) since the late 1950'a. F-Class started out by High Power shooters using a rest under their rifle's fore end slung up in prone; they, too use full length bushing dies. Benchresters started using full length bushing dies a decade or more ago. And Sierra's been testing their bullets with full lenght sized cases since the early 1950's.
