What I've seen that I would call a splash back I've normally seen on yotes. From a round that was sort of hyper (22/250, 6/06 you know) and pretty much on two different angles.
Angle one, a yote comes in and is taken quartering to me.
Angle two, a yote comes in and I take him head on, thus hitting what I call the breast bone.
Holes can be wide and narly looking, bullets go on thru and the yote hits the turf absolutely right now!
