Ebay can still yield treasure...
I am an old school reloading tool guy and like Lyman 310 tong tools. On Ebay a guy had up for sale a full Lyman 310 kit, with original 60's box, tool, adapter and a full set of dies. He did not mention caliber and an email yielded no answer. I close look told me it was 303 British, so I clicked the "Buy It Now" for $50.00.
It arrived today and sure enough it was 303 British. The good thing is this die set and handles can also load 30-40 just fine as the case adapter and priming die are the same. With another case adapter and priming die (which I have) it also loads 308 Win. and 300 Savage. The set also contained the right case neck expanders for both jacketed and cast bullets.
There are still over looked treasures and bargains on Ebay for the fellow with a sharp eye and a quick forefinger on the mouse.
