You've come to the right place. The following info will help in getting the right answers (or several variations of the right answers that you will have to sift out and make one or more of them your own)
Model of Traditions gun? This helps with barrel twist and other oddities that may be particular to that model.
Type ignition (flint, perc, inline)
any idea what you want to burn in it? black powder or subs
any idea what projectiles? balls, powerbelts, conicals
Your budget. This helps as to what guys recommend. Some of us are pretty cheap too.

This is the best tome to ask questions here. The number of guys on here has at least doubled since about 2 weeks ago. The flinter season gets em all wound up! On the Traditional forum there is a Tips thread. Lots of goo d stuff there too.
Take a look back thorough all of the old posts and you'll find all you need to know and more. I just purchased a T/C Firestorm two weeks ago and found the research very helpful. After your research, ask any questions you might not have found. By looking at the topics, you can really narrow down the information to your weapon.
