As RPbump says, youll need to experiment in this arena to determine what will work & what will work the best.
On caveat though. Some shooters have experienced case separations in perfectly good brass or brass that hasnt been shot much when using wads.
The current thinking is that an oversized wad will stick or drag along any BP residue, stretching the brass , & eventually causing a separation.
Who knows whether this is true or not; however, it does make some sense.
Just something else to keep in mind or fret about
