You have been a great help to me with valuable info, andnow maybe I can help you. The gun you have sounds like the exact gun that I have. First of all, which discs does the gun take (orange or red)? If it takes the orange ones, that is an older gun (like mine) and can be "upgraded" to the Extreme ignition (which I did)that uses the red discs and has a improved breech plug.The discs can be reloaded several times, but if you choose, there is a conversion to #11 ormusket caps

As for loads, I shoot 130 gr Pyrodex and 250 gr Barnes Expander and have had great luck. I can group 1" or under at 100 and 2" or under at 200. I have shot 100 gr Pyrodex with 250 gr Expanders with similar results. I chose the 130 gr load to hunt with.

I hope this gets you started, and I'm sure there are guys with more experience than me that can expound on my limited knowledge.
