The Crosman 150 is my favourite and most accurate CO2 gas powered pistol. Most gas pistols become inaccurate before the capsule has fully depleted meaning you have to stand there cocking and shooting the empty pistol until the capsule has emptied enough to allow it to be removed from the gun. My 150 remains accurate until the last few quieter shots which register low followed by a little hiss leaving the capsule completely empty and ready to remove.
I also find the sights are better on the 150 than those of the Benjamin Rocket and the loud crack when shooting only adds to the experience.
