Proper practice targets?

[NetNinja]

I have found an indoor range that goes out to 25 yards but sadly not 50 meters. What would be the equivalent target to be shooting at to compensate for not practicing for 50Meters?

I have been shooting at 50ft small bore targets.
Or continue to practice 3 position using 50ft targets?

Thanks
