Raimey,
Search on the GGCA forum and I think you will find it. As for annealing, I just hold the head/rim in my fingers and twirl the case in the flame (with the torch standing on a table or the floor) and drop it in a coffee can half- full of water. You can't hold it long enough in bare fingers to soften the head. Other people criticize my antique method and insist on buying some motorized device to do it. BTY if the barrel is marked 6.8mm bore diameter, I agree that it should take larger than .261" bullets, but you should "slug" it anyway.
