I use bushing dies in several calibers. I love them. Neck tension becomes yet another factor to use in fine tuning for ultimate precision. At the benchrest matches I have attended you see primarily two types of dies. 1 - Customs that are ground (reamed) to produce an exact fit for a given chamber and 2 - FL sizer with neck bushings from brand X. I am a Redding guy myself, but other good choices as well. If you are seating bullets in the lands, then you usually want minimum tension. Redding recommends measured size minus 0.001" for the bushing. The older and harder the brass gets the more you have to resize it unless you anneal. I usually shoot with 0.001 or 0.002" undersize with all my VLD bullets. I run a little more neck tension on bullets that jump.

My 2 cents, tim
