I just found my tatered copy of his famous book and also, found my explosive bullet setup he made for me, way back when along with the hollow pointer. I corresponded a lot with him back then and his son is a member of Graybeards outdoor forum and posts there regulally. I owned one of his shoulder holster for a 8 & 3/8" 29 also. I recently, hybridized a model 15 with a K22 cylinder reamed to .224 Harvey Kaychuck and k22 barrel to shoot his famous caliber, that I read about sooo long ago. Plan on rereading this book in near future.
