[QUOTE="SidecarFlip, post: 915977, member: 39764"] Yes and no. SOP is a touch on the shell holder but, it's going to depend on how much you want to set back the shoulder (non-belted case). An important note is NEVER contact the base of a pistol die with a shellholder. Pistol dies are usually made with a carbide insert and it's very brittle. Contacting the base with a shellholder during a resize operation will fracture the carbide and make the die unuseable. Even a non bushing die is capable of setting back the shoulder depending on how far the brass is inserted into the die when resizing and the height of the shellholder in relationship to the bottom of the die itself. Dies are machined to SAMMI case specifications but that don't mean all are exactly at those dimensions which, is why you need to compare a fired case to a resized case (shoulder datum) to ascertain the setback (usually 0.001-0.003 to allow for easy extraction after firing (in a bolt gun). Semi auto's aren't that touchy and don't require a datum measurement. Just bang them out and don't get excited. The sloppy semi auto action requires no extra effort. You'll find that most all my reloading dies will be ground off a couple thousands at the base end just for setback. [/QUOTE]
