Not quite true. Even today, our modern day "practice ammunition" for aircraft delivery, artillery delivery and rocket delivery, are what are called sub-calibre. In other words, smaller, lighter and cheaper. Yes, they are more affected by local meteorlogical conditions, but they are typically used to practice procedures, rather than accuracy. In order to practice accuracy, you practice with the real thing.

Even during WWII, they used practice bombs. My hometown was a major training centre for the Commonwealth Air Training Plan and housed part of the bombing school. Just to the northwest was the full bombing school. Anyways, they dropped metal bombs about the size of a coffee can weighing in about 8 pounds. The bomb was aerodynamically shaped with a hole in the back where a phosphorous tracer was placed to allow for tracking the round by the bombardier. Just to the west of my home town, a fall dance was ruined by it being bombed by a bunch of these practice bombs. The lights from the dance were accidentally confused by the aircrew as the target on their range and they dropped their ordnance. They killed one person.

So, in WWII and nowadays, practice munitions are all round us.
