That is 2 different questions. Traditions has an inexpensive ML but you get what you pay for, IMO the tc encore is the best because of the oppitions that come along with it, buy one and end up with 100 defferent guns some time down the line as money allows. Just my thoughts.
I'll recommend the Lyman GPR in .50 perc. as a trad. ML and any kind of the Traditions break open ML in .50 as a modern one. The newest model is the buckstalker. It has break open system and is available in .50.
Like most everything else there is certainly something to "you get what you pay for". That being said I shoot a Traditions break action and have no problems or issues. I uncategorically reccomend it for someone just starting out.
rjr, I shoot a CVA Optima and would recommend it to anyone. It shoots great and is easy to clean. It fit right in with my budget as well. Whatever you decide on though, if this is your first, welcome to the world of muzzle loader hunting. I am sure you will love it.
Moose calling can get confusing to some, but cow calling is your main tool when moose hunting. If you go out and buy moose calls I would say you're wasting your money unless it is the birch bark cone. I find most store bought moose calls sounding worse than puffing a grunt your hands to make the call. You can roll up a piece of birch bark in a cone shape to use as a call and spend your money on a video that teaches you the basics of a cow call. A milk jug or a coffee can with a hole and a rope...
