Traditions 209 Sporter questions

[brendan]

I have a Traditions 209 Sporter that I have never used. I was wondering if anyone could tell me if this gun is capable of handling 150gr of powder since it says mag on the side of the barrel. I don't think I would ever use that much but I have no manual and would just like to know. Thanks in advance.

It was my understanding talking to a guy at the local sporting goods store that it is...but he seemed a little green in his knowledge.
