Help!! what has happened to Airgun after 1250 pellets

[shahsaeen]

I have a gamo cadet air rifle in .22 caliber. Its muzzle velocity is rated at 394 ft/s. I have used 5 boxes of gamo match pellets and 1 box of gamo magnum pro pellets. Initially the gun was acting quite weak like a lizard managing to run away after 1 good hit in the abdomen. To finish a lizard on an average 3 pellets were required. I had taken out 3 rats immobilizing them in 4 head shots and then using countless to finish them off. Doves required 2 shots and then running after them and catching them by hand. After 1000 pellets i oiled the gun. Then i used up 250 pellets. I took particular care to clean the barrel after each outing. Now using my 7th box i am experiencing a strange phenomenon. Lizards are split in 2 parts with 1 gamo match pellet. Doves are taken out in 1 pellet and we have to quickly slit the throat otherwise they are on the verge or dying. Now rats are immobilized in 2 shots and third shot finishes them off completely. I was amazed that the pellet now even penetrates its head skin. Now i ask what has happened to my rifle? Where has this lethal power come from? what is the phenomenon called? Is this what we call in urdu "Rawaan Hona"?

Meaning no disrespect... but 3 shots to kill a lizard??? Either the pellets weren't hitting the lizard or something else... In all my years of lizard-killing, I've seen a maximum of two hit shots, that too only once or twice. Most of the times, the lizard dies in one pellet, leaving a whole lot of mess on the wall... :P

However, just so you know, airguns take time to "break" in. Basically, the parts get fairly worn, resulting in working in better harmony with other parts. I believe it is not very surprising to see a slight increase in velocity. Plus the gun becomes more consistent and accurate with time.

Hope that helps a little.

Have u recently adjusted the site/scope of your air gun?

The dried grease inside the barrel could be the probable cause. The oiling did the trick.
