The S410 is the 10-shot version of the S400 precharged pneumatic, but it also has the added benefit of adjustable power. You'll get about 60-80 shots on low power and 30-40 on high. The power adjustment wheel is located on the right side of the rifle. The low end delivers about 600 fps, the high about 920 fps (.22 cal.) The variable power makes this a much more useful gun for dispatching small and large pests at distances other guns can only hope to achieve! On the top end, you'll see remarkable energy in the range of 30-35 ft-lbs. This whopping power will serve you well when the time comes to quickly and humanely dispatch pests. Of course, power is nothing without accuracy. And, this gun has it in spades! It comes with a 12-groove Lothar Walther barrel, the cream of the crop when it comes to accurate barrels. If you do your part, the gun will do its part every time! And, the shrouded barrel helps deaden the sound so the report won't spook the very critters you're hunting. The two-stage adjustable trigger lets you customize things according to your own needs. It also has a quick-release charging connector. Manufactured in Air Arms' state-of-the-art facility in England, the S410 sets a new standard for accuracy, power and versatility in precharged pneumatics.
