How many pellets?

I have a question about the load that I'm shooting out of my CVA Wolf... Currently, I'm shooting 100 grains of Pyrodex pellets with a Thompson/Center Shock Wave 250 grain sabot... Is that gun capable of shooting 150 grains of pellets or should I just stick to 100? I've killed a few deer with what I'm shooting now but I'm pretty positive that I've only ever had one pass through... I was hoping that bumping the charge up to a magnum size would give me the results that I'm looking for



What are your thoughts? Thanks for your time, guys
