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.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
