Like Jim said, your setup is right along the lines of what most shooters use. I personally have a Stoeger 12ga coach gun and a pair of .44 1860 Army replicas. I don't have a rifle yet; I borrowed a friend's for the one match I've been able to shoot. Loops on your belt for shotgun shells are really helpful - I just carried a satchel of shells, and I lost some time getting them into the correct orientation to load.
