RE: Wads
I almost always find greater velocity,accuracy and consistancy with heavy hunting loads when using wads under a PRB and often with conical's. You just need to try. With a PRB, the wad really prevents blowing patches. Also helps keep leading down to a minimum with conicals as well.
As Roundball mentioned, I have also switch to the next caliber wad diameter with very good results.
