[QUOTE="tatco, post: 486873, member: 28143"] Usually bushing dies are used by guys that have custom chambers with tight necks. Sounds like your chamber is at the upper end of the SAMI spec. A full length Sizing die will do the job. To determin what bushing(s) your "Bushing Neck Die" needs. Get a loaded round(factory will work to get you in the ballpark). Measure the neck diameter about a 1/4" down from the top of the neck. Then subtract .002 from that diameter and you'll have your bushing size. If you sort your cases into lots by weight you'll have some consistancy in neck thickness. This will help you determine the correct size for your different brass. If you don't have a ball mic to measure your brass neck thickness, then use a full length resize die and your seater die to load a dummy shell for each of the different shell manufacturers. Then measure the diamater of each one and subtract .002. and see if they are the same. You will find that Lapua brass is thicker than the others and needs a different bushing size to keep your bullet grip consistant. [/QUOTE]
