Hornady Annealing Kit - Manual (Page 7)

8. Insert marked, empty case in tool. Start power driver (if using a hand drill, it is
most convenient to lock the drill in the ON position).
9. Bring spinning case into flame. Locate
middle of case neck in center of flame,
near end of bright blue inner cone. Always
locate flame on neck area only. NEVER
APPLY FLAME DIRECTLY TO CASE BODY OR
MARKING MATERIAL. AVOID CENTERING
FLAME NEAR CASE SHOULDER.
(See photo B.)
10. As case spins and heats, observe condition
of temperature sensing material. When that material melts the case neck,
it has been sufficiently annealed. FURTHER ANNEALING ONLY SOFTENS
THE CASE SHOULDER WHICH CAN REDUCE ACCURACY AND CASE LIFE.
11. Immediately and quickly dump case into water by moving and inverting power
driver so that case falls out of Hornady tool and into water container. (Avoid
tipping the torch and avoid getting the power cord near the flame or hot torch
tip.) RAPID COOLING DOES NOT IMPROVE ANNEALING. IT IS NEEDED TO
PREVENT ANNEALING HEAT FROM MIGRATING TO THE CASE HEAD. NEVER
USE ANY CASE WHERE CASE HEAD ANNEALING MIGHT HAVE OCCURRED.
12. Insert another case in Hornady tool and repeat process. For maximum uniformity,
continue until all cases in that batch are annealed.
13. It is worthwhile to tumble all cases after annealing. This dries and
removes heat-generated scale and further cleans cases.
