With pellet rifles, strongest is not always best. There are rifles such as the Air Force Condor that claim velocities of 1400 FPS from compressed air- others that inject a drop of oil that is burned (dieseling) and get higher velocities (technically those are a firearm, just like a .22 rim fire) HOWEVER-
When a pellet is driven faster than 1100 fps, it is supersonic. It WILL slow down, and drop below the speed of sound. As it drops back through the shock wave at the speed of sound, the pellet will be disturbed, and accuracy will suffer badly.
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.
It depends on your definition of Airgun. Are you asking about Air Soft or Pellet gun? The strongest Pellet guns are in the PCP ( Pre Charges Pneumatic ) class of air guns. These require a scuba tank to charge them to 2000 to 3000 PSI and can fire up to a 50 caliber pellet.

First, check to see that you have a BB gun, and not a pellet gun. Both pellets and BBs are made in .177 cal. A pellet gun will not shoot BBs (in most cases) If your gun IS a BB gun, you will need a gunsmith to check it for damage, stuck items in the barrel, etc.
The 620 is a 4.5mm or .177 caliber pellet rifle and is rated around 450 FPS.
I assume you are asking about air guns, if so then it would be helpful if you stated the model. Most air guns can accept all weights of pellet grains as long as the pellet is the correct caliber. In other words you can not use a .22 pellet in a .177 caliber pellet gun but you can use different weight pellets as long as they are .177 for that gun.
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.
You can purchase .177 pellets at most any sporting goods stores. "Big 5,"' Dicks" or Wallmart just to name a few. As for the age of the Pellet gun you will have to give more information about the "GUN" (It not a rifle?) to determine the age. If you are asking about the model 177 then it was made between 1935-41
Not necessarily, but similar. An air rifle can be a BB gun, or it can be a pellet gun. Pellet guns are rifled, have more power, greater accuracy. .
use a .177 cleaning rod to force it back into the breech.
