Case Neck Annealing Kit PRODUCT INSTRUCTIONS
Reloading is an enjoyable and rewarding hobby that is easily conducted with safety. Carelessness or negligence can make any hobby hazardous. All Hornady reloading tools and supplies are designed with the user’s safety in mind. However, since Hornady Mfg. Co. has no control over the manner in which products or components are used in the reloading operation, we cannot assume any liability for damage which may result from the use of the products or the information given herein.
CASE ANNEALING Never apply heat to any loaded cartridge or primed case. Always verify that all cases you intend to anneal are empty and unprimed. Do not assume an indented primer is spent. It could have been a misfire. When heated sufficiently, such primer will detonate, ejecting the cup with dangerous force. Examine all cases to be annealed. Discard any case with cracks or splits, enlarged primer pockets, serious dents, corrosion, or excessive thinning between the body and the web.
BENEFITS OF CASE NECK ANNEALING When case necks become work hardened and brittle due to repeated firing and resizing, annealing effectively extends case life. Within any batch of fired cases, variations in neck hardness will be found. This variation in hardness contributes to variations in bullet pull. Proper annealing reduces this variation and improves the uniformity of bullet pull, which can improve accuracy.
Case is too small in diameter for the holder. Case is too short for the holder. Case fits freely and is the correct height.
ANNEALING PROCESS 1. Clean excessive debris from empty cases using a vibratory tumbler and cleaning media (Hornday offers these tools). Clean cases are easier to inspect and they heat more consistently and show change in the temperature sensing material more clearly. 2. Visually inspect all cases. Verify that no case contains any of the following: Primer cup, powder, debris of any kind, obvious defects, split neck, excessive thinning near web-to-body juncture. 3.
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.) B 10. As case spins and heats, observe condition of temperature sensing material.
