[QUOTE="Gene, post: 485167, member: 7402"] The necks are stretching because you are F/L sizing the shoulders down too far, creating excessive headspace. Turn your die up a full 360 degrees, and go slowly down again about 1/16" at a time until die barely touches the shoulder. Try the case in rifle. If bolt turns down hard, move down another sixteenth. Do this until the bolt closes with very mild resistance. The bottom of the die should be somewhere near the shell holder, not necessarily tight against it. If bolt flops down, you sized case shoulder too far. Use very light lube in and out of brass neck -shoulder area. [/QUOTE]
