I anneal my brass (308 and 303) by holding with my fingers and heat the shoulder until the heat spreads down the case body and the neck becomes dull red then dump it in a bucket of water. I use the pencil flame to do the heating so its very quick. I do several hundred at a time this way. For the 303 Britishicon I am getting over 10 reloads with ease unless the BREN eats the brass.
