[QUOTE="Mikecr, post: 318505, member: 1521"] Sounds like you're committed. You must have already considered what you want.. You want uniform necks with not alot more than 2thou of sizing needed. So what do your fired necks measure fresh out of the chamber? You'll want your loaded necks to measure ~1thou less after turning. So if your chamber neck is .334" you'll be good with LOADED necks measuring .308 +24(.012x2)=.332", leaving FIRED brass measuring .333(after springback), and 2thou sizing to get .331, providing ~1thou tension(after springback using a .3300 -.3305 bushing). Or take your [(chamber neck - .308 - .002) /2] for a thickness starting point. [/QUOTE]
