Air Rifle pellets come in 4 basic types. Flat nose(Wadd-cutters) for targets. Pointed for distance. Hollow point for hunting and Round point pellets are a universal pellet. They also come in different weights. Light weighted pellets will fly faster but have a tendency to drift off target over a long distance. Heaver pellets fly slower but straighter as a general rule. Obviously a heavy pellet has more knockdown power than a light pellet.
You need to try different pellets in your rifle. It has been found that some pellets respond better and differently in different air rifles. So you need to try a variety to find out which one is best for your rifle.
The best for what? Paintball, .177 Pellet, 6 mm pellet or bb rifle?
As long as the pellet is .177 Cal then any .177 caliber pellet will work in your .177 Gamo.
No. a 177 is a 4.5mm pellet. A 5mm is a 20 cal pellet. A 5.5mm is a 22 cal pellet Don't try it in the wrong airgun.
Use a .177 cleaning rod and push the pellet back out of the loading port.
Different pellets have different purposes so there is no BEST pellet. But I suggest that you stay away from cheap pellets they perform poorly. High quality pellets like H&N .177 8.18 grain Wadcutters, will cost you around $12 (USA)
The best brand of .177 caliber gun that is good for hunting will depend upon what type of hunting a person is doing. Two good brands for general hunting are the Daisy and Crossman.
Any air gun or rifle that uses a .177 Caliber pellet can use the Gamo .177 Red Fire Pellet. No matter who makes the air gun. The Caliber .177 is universal to all .177 caliber pellet guns or rifles.

Simple: With the Safety On. Slide a cleaning rod down the barrel to dislodge the pellet from the loading port. Yes there are cleaning rods for pellet guns. They are 177 caliber.
With the right pellet you you can, But it should be a hunting Pellet (Hollow-point) and it should be a heavy pellet not a light weight pellet with at least 900 to1000 FPS.
