The KEN WATERS had a 99 converted to 7-30 Waters by Michigan Gun Smith, Wayne Schwartz. It had a full length for end, straight butt stock, 23" octagon barrel with a vent rib. He used a 22 Hi-power for conversion. Rifled with 1 in 10" twist.
Wayne Schwartz rebarreled a small Martini with a .30-30 bull barrel for me back in '81. It was my cast bullet offhand rifle for quite a while. He did superb work. He and I also ran the scoring shack at a couple of Cast Bullet Association cast bullet national matches. Heckuva nice guy.
