Thanks for the replies everyone! The load was:

200 grain Shockwave
MMP tan .45/.40 sabot
80 grains T7 FFFG
T7 primer

The rifle is a New Frontier Cascade Magnum. It is very similar or identical to the old CVA Hunterbolt Magnum I believe. They don't make them anymore. I removed the ramrod and used Acra Glass to bed the action. I carry a range rod over my shoulder instead of having it in the rifle.

I was really bummed out because I wanted to take my new Knight Vision out for this hunt but developed a problem with it which I will post about in detail later.

Today was a nice day, saw some deer but none came home with me this time. My buddy saw 3 bucks including a huge 10 pointer, but he had already used his buck tag so he was SOL :).
