[QUOTE="Guest, post: 25318"] Howdy Brent To properly spec a reamer you need to have the brass in your hand. Measure the brass O.D. about .300" above the base. Define your reamer diameter .0015" larger than this measurement. Define your reamer diameter where the body meets the shoulder based on the brass dimension (+ .002"), or your chosen wildcat dimension. Make sure you have at least .015" taper in the case body. One degree on the lead is what we prefer. The resize reamer should be .0015" smaller than the chambering reamer at the case head, and .0025" smaller where the shoulder and neck meet.
