[QUOTE="Lefty7mmstw, post: 911442, member: 48043"] Are you setting your sizing die to compensate for the shoulder position if your chamber is a few thou. long?? I had to turn my sizing die out a bit as my stw's chamber was cut with a nearly new reamer. If I don't set my die to the shoulder location I'll have the same issues you do Bob- .015" stretch per firing and two firings to the bright line just above the belt; as I'm loading now, .003" stretch per shot after the first firing and the 400+ casings I have will outlast two barrels. Set your sizing die to bump the shoulder two to three thou. and you'll get better than five firings per case. If you don't have tools to measure simply turn your die out a full turn and run a lubed case ( 1x fired) in that you have used a candle or match to smoke the shoulder on. Then proceed to turn the die down 1/16 turn at a time until the die is just kissing the brass shoulder. Try it in your rifle, and adjust just a bit further down if chambering is tough. [/QUOTE]
