You can purchase a Gamo air rifle at your local Walmart retail store. You can also purchase one online from the Amazon website and have it shipped directly to your house.
The Sheridan Blue Streak air rifle uses a 5mm pellet. This is about .20 caliber- larger than the .177 pellet, smaller than the .22 pellet. I have been able to get these at Bass Pro Shop. There are also at least 3 lots of them for sale on Ebay right now. Only the 5mm/ .20 caliber pellets will work in your rifle- do not try to substitute anything else. P.S. Have had one for years. These are extremely good air rifles- very accurate, very powerful.
You have to be 18 to purchase one
Never put more than one pellet in the barrel of a rifle at any time. Break barrel rifles only hold one pellet for each shot. There are some air rifles that hold several pellets in a clip and are fired one at a time. These rifles are usually have C02 power plants. Break barrel rifles are spring or nitro piston systems.
It's a 16 shot BB repeater or a SINGLE shot pellet rifle
A spring powered system uses a spring that is inside an air tube. The spring is attached to a piston. When the rifle is cocked the spring and piston are drawn back and locked at one end of the air tube. The other end of the air tube has a small hole that is directly behind the pellet and rifle barrel. When the trigger is pulled the spring is released and it pushes the piston down the air tube forcing all the air through the hole, and that fires the pellet down the barrel.
Atticus allowed the children to shoot tin cans with their air rifles.
I think you have to identify your definition of power. Do you mean speed or knockdown power? A .177 caliber pellet will travel faster than a .22 caliber pellet but a .22 pellet will have more knockdown power. With 200 GDP ($324) you should be able to find what you are looking for. I suggest you look at the web site below and read the owner reviews. Then you will have more information about your selection.( See the related link below)If this rifle is avalable in the UK then this one has the most power I've seen in an air rifle that is not a PCP class rifle. Its the "Benjamin Trail NP XL 725" its a 25 caliber Nitro piston air rifle.
You are saying both "Pellet Gun" and "Air Rifle in the same question." If it was a rifle it would most likely fall to the "AIR FORCE CONDOR" at over 1400 FPS, using a .177 barrel. (It has 12 different barrels that fit the rifle) Pellet guns are not as powerful as rifles. The EVANIX HUNTING MASTER fires a .22 cal pellet at 1000 FPS. The Fastest .177 air pistol that I know of is the Crosman 1720T Target pistol that is rated at 750 FPS. By the time I answer this there may be one faster Don't confuse speed with accuracy. Olympic class air pistols like the "Feinwerkbau P44 Match pistol" only fires at 508 FPS but is dead accurate and only cost $1,696 dollars.
Unfortunately their is no master record of every model air rifle made by model number that is compiled into one list. You will have to give some sort of description of the rifle. Is it a spring powered air rifle or C02 or Pump? Is it made out of wood or plastic? It is a BB or a Pellet air rifle. How long is it? About how old is it? Does it have any markings on it other than the serial number? Is it a multy or single shot rifle? without more information it is not possible to answer your question.
