[QUOTE="Derek M., post: 712219, member: 2693"] Best thing I ever did: buy full length size dies. Pick a brass brand and stick with it. Send your sizer dies back to manufacturer with a dummy round, preferably your bullet of choice. Have them hone the neck of your die to 0.003 less than your loaded dummy. Don't use the expander button/ball when resizing your cases. Runout is about non-existent. Size them, trim them, deburr, and load them again. I anneal after every 2-3 firings now. Bonus #2 is if you can have a barrel chambered with a neck about 0.002 to 0.004 greater than your dummy round. So, when sizing again, there is only 5 to 7 thousandths of total neck change from fired to sized case. This greatly reduced work hardening of the case and extends its life. I'm a fan of full length sizing. You can run into concentricity issues with a neck sizer die while using the expander, unless your dies are custom made. [/QUOTE]
