30 feet - I think shooting practice at that range should be done without using the sights, without taking time to aim, raise the gun and fire 2 shots in 2 seconds, just point shooting. That is how I used to practice when shooting at 10 yards. You should be able to hit a paper plate with both shots in that manner. I also used to close my eyes, opening them only when starting to raise the gun. Obviously it needs to be an appropriate sort of range for such drills.
