Garnet sand is similar to chromite, zircon in density. Used in sandpaper and sandblasting applications.

As mentioned above metallic fill is not allowed in br ,garnet doesn’t pack well so Is not a great choice for a rear bag .chromite is about .50 lb . shipping is the tough part .if chromite is not an option sand would be preferable to plastic or rice or any of the other mediums mentioned as they offer nothing positive in the accuracy dept other than they keep the gun off the bench .they tend to transit harmonics from recoil back to the stock rather than absorb them causeing stray shots .
