As they had previously been fired and of unknown loading history, I decided to anneal them, then run them through the Full length sizer with a tapered expander ball.
My set up is pretty primitive by some standards seen on various You toob videos, consists of a Primus LPG gas soldering kit, a cordless drill and a 12mm 1/4 drive socket mounted on a small extension shaft. The heat sink I use is pretty innovative, I think you will agree, simple but effective.

I did the whole 100 cases and never split one. I think they came out ok, most will probably get lost in the thrill of the hunt.
