Charts to show time to target with different BB weights with the standard NASF Joule ruleset.

This chart does not:

• Take into account accuracy.
• Take into account how heavier BBs are more resistant to wind drift.
• Go further than 120 meters.
• Care that your hopup cannot hop that far.
• Calculate time after the BB stops moving faster than 5m/s.
• Give an estimate effective range.

Your effective range is defined as how far away you are able to make reliable hits.

For a reference of how much time the differences actually represent see this video.
