    I have a good set of Pins. McMaster Carr carries pins of many sizes so one doesn't need to buy a whole set if they know what sizes they need or want.

    I almost think the op's talking about buying pin gages to use as expanding mandrels..... I'll _guess_ the technique would be to grind a taper on them and ram them into necks as expanders???

    guessing here... but don't see why it wouldn't work.

    Care to explain TrxR?

    I made some from drill rod, chamfer and polish. I put them in my rcbs bullet puller collets and use them as expanders. I made mine .001 less than bullet diameter. Enough elasticity that they end up .002 less (.308 cal Id make a .307 pin). Perfect for my needs.

    You can get just the size you need. Dont need to buy whole sets.
