yes i will get some glasses sorted does it sound about right that the pistol will not penetrate a plastic bottle or could this pistol be underpowered i have no other experience with pistols so i am unsure on what the power should be like? Also its not that accurate but i am putting that down to the pellets as i have looked and certain pellets do not seat correctly if that makes sense so i am assuming this would be causing the pellet to fly off a certain way as some of the pellets shot dead straight?
