That light of a powerbelt may not be the best for 200 yard shots. If you sight in 3 inches high at 100 yards you should be close to dead on at 150 and 3 to 4 inches low at 200. Basically a point and shoot out to 200. Make sure you remove the plastic cup, lube the rear post, and put the cup back on the PowerBelts to ensure the cup comes off quickly and doesn't cause accuracy problems.

I perfer the 250 ShockWave over the powerbelt.

Good luck.
