In the last months I was interested myself for the shot with air pressure and therefore I decided to write an article where I synthecize some of the things that I was to know so far. In Portugal any bigger citizen of 18 years can buy a free air pressure of acquisition. A free air pressure is of acquisition will be of 5,5 bore 4,5 or and if the energy of the projctil to the exit of the 24 pipe will be inferior or equal joules. The shot with air pressure alone if can make in private properties, to the use or the transport of air pressures is not allowed in public places. The law is not very clear on the conditions where if it must carry through the transport of air pressures. The air pressures must be carried from form the one that is evident that its immediate use is not possible, said common-sense that the air pressures must be carried in a luggage or a stock market, without being municiadas and without being armies, being folloied of the ammunition (lead) and with cadeado of trigger applied. Who makes the transport of air pressure has that if to make to follow of the respective invoice so that it can prove that he is proprietor of the same one. A thing that at to certain surprised me form was the power that a free air pressure of acquisition obtains to have. To initiate me in the shot with air pressure I bought air pressure metallic Comet 400 and some targets. At a distance the one that was to shoot against the targets, that were of about 20 meters, Comet 400 made amolgadelas in the targets, it took what me to buy a Gamo Fox Delta to use specifically with those targets, because is a much less powerful air pressure that Comet 400.
