This was posted in a gun group on Social Media. They were shot at 7.5 yards. While not terribly challenging it does require some amount of skill. Especially in recovering them after being shot. The .45acp brass was pushed into the holes of a cardboard target and shot at again. Below is a photo of a clean hole through  one of the casing.

Another person posted this photo and said this was shot at 1300m. He did not mention with what gun and what caliber it was shot with. Can any service man or woman ID the 40mm round in the photo? Is it just a training dummy round?
