[QUOTE="highdrum, post: 1731294, member: 13732"] I use a bushing typically 2-3 thou under loaded diameter, i have carbine and ti-N expanding mandrels(1 thou under bullet od) and neck turning mandrels(2 thou under bullet od) I don't neck turn yet......but plan to start doing so to clean up the neck inconsistencies, as I believe that's where some my runout at neck is coming from. I do not lube necks prior to running the mandrel into the neck, as carbide and ti-N don't really need it. I DO however set up my mandrel die as high as possible with just enough depth to fully size the neck with ram of press at full stroke. I dip the bullet into graphite dry neck lube prior to seating. Most all my rounds are loaded with 2-3 thou neck tension. I haven't noticed a lot of difference in groups. I do believe my reloading practices are a lot better than my shooting though. I get low teens to single digit SD, and upper teens ES but only manage 1/2 to 3/4 moa groups. I need more trigger time....... [/QUOTE]
