Well... not quite yet. Sometime back I sent a CZ Bobwhite 12 ga. to J White Gunsmithing for conversion to 45-120-3.25. The plan is to regulate for 480 gr at about 2100 fps. Jim machined a new monoblock so I should still have the old 12 ga. tubes/block. I received an e-mail from Jim last week stating that he should be shipping the finished product in a week or so. Needless to say, I am excited at the prospect of finally owning and shooting a double.
