You have to watch those reviews as well. If anyone gives you a shot count chronied under 295, it's not worth much. An extra 10-15fps over a tank can make a big difference. Needless to say I don't see many other people getting those results yet, so I don't believe it. "About 1500 shots" isn't the same as "1500 shots give or take 20 balls"
It's all about the angles.
