Howdy,
I'd like to modify Doc's statement.
The Henry Big Boy is in a state of flux. It was not approved for use by SASS.
However, it has been used at local shoots (not ours) and SASS continues to take advertising from Henry. In fact, I believe that a Big Boy was given out as a prize at End of Trail. So, if you must, then proceed at your own peril. The future of the Henry BB is far from certain.
I would agree that a Marlin is a great gun for beginners and old-timers too.
Adios,
