[QUOTE="Frogman77, post: 404792, member: 15339"] I think I might have figured something out, although it's still problematic. I took a known case to have low runout, seated a bullet 5 times and consistently got a seated round TIR of .001 or less. So I think my sizing and seating process is sound. then I annealed the case to see what would happen. after annealing, my sized neck TIR still remained .001" but after seating my TIR on the loaded round measured .0025-.003" I'm using 650 deg F tempil stick about 1/4" below the shoulder and a propane torch. Rotating the case in a drill until I see the tempil stik just change. Why would annealing cause increased runout??? Could it be because I annealed when it wasn't necessary? Would that change the characteristics of the brass that much?? Any Thoughts?? [/QUOTE]
