[QUOTE="Hugnot, post: 2337815, member: 115658"] My guess is that the anneal process reduced the effects of work hardening that occurred when the ogive of the bullet was formed. The bullet was toasted for about 2 minutes with probably a propane torch at probably 2,300 plus degrees. Upon sectioning some bullets & looking at the insides I often see longitudinal ridges separated by striations at the ogive, rarely continuing to the exterior, my guess these are the beginnings of stress fractures - formed at right angles to ogive forming compression. Toasting the bullets at 2300 plus degrees would reduce the effects of work hardening and also reduce the tendency of the bullet to fragment. Good method. [/QUOTE]
