Looks like low brass to me personally I would use them on dove ,skeet ,etc. I always use "High Brass" on rabs.Just to give that little extra through the weeds and grass.JMHO
If you can pick them up with a magnet, they are steel based. If the shot size, i.e., 4 ,6, 71/2, 8 etc. isn't displayed on the cartridge hull, then it is definitely a reload.
