SHORT THROAT OWNERS--Who's up for chipping in for a reamer to fix our issues?

[nincomp]

I do not know if anyone is confused by the PTG reamer drawing, but the print uses different nomenclature than most of us on the site. We refer to a compound throat. The print calls the first part of the compound throat the "lead." What can be confusing to those making chamber casts is that the rifling can be seen well before the end of this "lead."
