Mr. Corbin, Dave has a web site, several actually, this one is swage.com. On that site there is a directory of bullet makers. (Who use Corbin equipment, surprise, surprise!!) At the bottom of the listing there is listed the calibers of bullets that maker supplies... I suspect you can find a half dozen that can furnish your requirements in no time at all. And one may have some "on the shelf."
As I recall, Barnes (long since "sold out" to a man whose name I don't recall) had in his lists bullets of this description in several jacket thicknesses... His address should be in the back of Gun Digest annual in that directory. LUCK.
