I keep seeing people advertising once fired brass.. is this only brass from reloaded ammunition or can you sell on brass from factory ammo?

Anyone here used one, is it worth the money?

ust wondering if there are and 22 creedmoor shooters here hiding in the dark. Have a 22-250, will rebarrel and push the 69 tmks or 70 bergers at warp speed. For foxing etc so not concerned about barrel life (wearing parts!)
