The die with all the bushing is one with inserts that will size just the base also will use a wilson neck bushing,has bushing that will set the shoulder back.. The die on the far right is 7mag is set up for a shoulder bumping bushing also use it for my 30-338mag,264 and 338mag. The one with all the treads is made from cut off my barrel for a 222AI and the one on far left is match 308 from my reamer set up for wilson bushing.
