The target on the right has 2 each 3/8" holes , 3 each 1/2" holes one 7/16" hole, one 5/8" hole and one 3/4" hole. I usually shoot at this target at 20 yards because our winds here have been ranging from 10 mph to 30 mph. Hitting all holes with a scoped rifle is easy, not so easy with open or receiver sights.
The "bells" are 7 1/2" circular saw blades. They ring very loudly.
