Sorry for the late reply. Been out of town awhile.
I have the reamer and Kirby did the chambering. Dave Manson has the blue prints and will give them out with my permission (which you have) or if Kirby does the work, you can borrow it if you like. It is a tight neck though and factory 338 Ultra mag brass will not fit in it to fireform. All brass must be turned.
A friend of mine from Wyoming borrowed the reamer this year to make him a long range whacker and interestingly enough, his gun liked the same powders, same seating depths, same bullets, and same charges of powder when same lots were used. In other words, it seems to be fairly predictable for load development and I happen to have a TON of load data!
