Dave, from what I understand, the #3 in .357 was a limited edition commermorative for the California Highway Patrol. Now wouldn't that be a neat one with heavy cast bullets? I had a #3 in 45-70 but sold it to finnace my Pedersoli 1874 Sharps repro and I still have my #3 .22 Hornet. They are neat rifles.
Be popular? Heck, I have enough friends.
