Yeah, you sold me on felt wads, Marrakai.

But soon I intend to try wads cut from a coil of 5/8" diameter backing rod. It's closed cell foam and pretty tough, yet lighter than either Kynoch "store-bought" foam wads or foam wads I make for myself.

I already tried backing rod in my .500BPE (1/2" diameter)

The stuff comes in 20 foot coils, and you just cut off whatever length you need to fill in the case. Very easy and convenient!
