Well I found a box of Lyman dies for .40 S&W/10mm, but it's missing the sizing/decapping die. There's a chance that one is still installed on one of about twenty presses that I haven't had a chance to fully inventory. The set is Lyman # 768027, $92.50 list at Lyman. Lyman sells the sizing die alone for $41.95. I'll let the set less that die go for $25, +shipping, or you can pick it up at my place in Fairview if you're in the area.
