Reloads is when someone takes the empty casings ( shell ) and refills them so that they will shoot again.. My guess is that they are reloaded ones as well. They should shoot fine though.. Most steelshot shells will say so on the outside of them.. As well as most reloaders uses lead shot when reloading. They look alot like skeet shells to me but should work fine on grouse and wood****.. I know nothing about dove hunting as it is not legal here..

Someone say paper? Here is a few, mostly 00 Buckshot and the bird shot still had a star crimped on them. One of these is a slug, I have more but you guys get the idea...

another pic from a different angle.. Some of these old paper shells will say Kleanbore and extra long range instead of smokeless or magnum loads.. These look nice beside my old flintlock double barrel shotgun...
