[QUOTE="Kevin Thomas, post: 473711, member: 15748"] It's a tapered mandrel, useful for rounding out case necks and uniforming IDs, either for seating or for neck turning. Sinclair's sells a die specifically for this, as well as a selection of mandreals in all common bore sizes. Actually, they sell two; one for sizing and one for neck turning (same mandrel is ised on their turning tools), with the turning mandrels being .001" smaller than the expanders. They're great for rounding out case necks digned by ejection (especially prevelant in gas guns) and even the minor dings we get in new brass from shipping. Everyone should have these on their bench, and they should be used a lot more than they are. I'd take a look at these as a start, but I think that'll likely cure the marking problem. [/QUOTE]
