I was extremely low tech when I first started annealing using a shell holder a battery drill and a canned gas burner I sure junked allot of cases as I went by the blue ring that appears when annealed correctly (303 cases) its only a split second from good to junk I got it fairly close but the results more often than not were not the best.
So saved for a year and got the AMP machine as when your feeding 3 F class rifles, a full bore rifle, a 308 field class rifle and 5 303's all banging away throwing lead the cases just pile up.
