"It's only easier to remove non-fired bullets and pellet-powder"

That is so funny to have people think so. My brother tried pellets (Prodex) in his black diamond and they were crushed when he seated the maxi hunter bullet he used.
My T7 comes out as a compact wad from my Remington 700 and falls apart when it hits the can.

Soap and water works well with both and even in a inline.
