That's what most folks do with full length bushing dies.
I would have liked to see both Redding and RCBS to make their bushings a tight fit in the die as well as positioned to size the fired case neck all the way back to the shoulder. Sized case necks are better centered on case shoulders when this happens. These dies are really "partial neck sizing shoulder bumping body" dies because of the coupld hundredths inch of the case neck that doesn't get sized. Although the difference is small, it doesn't seem to matter much. Especially When Sierra Bullets uses Redding full bushing dies on all cartridges they're made for testing their bullets; standard Redding FL dies for all the rest.
