1.) Be aware this is not always necessary. Only if cases are extremely dirty and a lot of unburned powder is consistently found in chamber would you need to anneal. Use this method on 40-65, 45-70, 45-90 and 45-100.


2.) First place case in proper container filled with approximately 1 inch of water so head of case is submerged in water. (Reason is you only want to soften mouth of case and not head area as this can ruin strength at base and primer pocket where case must remain rigid to handle pressure.)


3.) Next heat case mouth (approx. top 1/2 inch of case) uniformly just to where it begins to turn a dullred and then knock over in water. A propane torch is usually used for heating device. MOST IMPORTANT: Remember if case gets too hot they are ruined and there is no way to make hard again. So, try a few out and get a feel for the proper color and softness required for your application. If they get bright red, you probably went too far.
