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.
200 or so ------------------------------------------------- The slowest BB gun ( NOT Airsoft or Pellet gun) that I know of is the Marksman 1010, it is rated at 200 FPS. The fastest BB gun I could find is the Crosman 2100 that is rated at 755 FPS. This gives you an average of 477.5 FPS Pellet guns and rifles can attain much faster speeds.
If it's a pellet gun them most pellet guns are capable of killing a squirrel. Check the FPS (Feet per Second) and if it's over 400 FPS that should be sufficient. Expect to pay $60 and up for a pellet gun. Crosman makes an excellent pellet gun that is rated at 610 FPS Called the American Classic and it cost $70. I also suggest using Hunting (Hollow point pellets) these will be the most effective.
FPS stands for Feet Per second. This is how the air gun is rated at firing a BB or Pellet. Every model has a different FPS.
No, a pellet gun can't kill a bear it will only make it angry. There for it will eaither attack you or just ignore it.
Well, the legal FPS for an airsoft gun is 450, but you can get snipers, AEG's, etc. that run up to 600 FPS and beyond.
350FPS would be sufficient
It all depends on where you are struck. But anything above 300 FPS can do damage Remember NEVER point a BB or Pellet gun at anyone.
750 fps./BB; 665 fps./pellet The name Power-line may be a little misleading. Modern Pellet rifles are capable of firing a pellet at 1000+ fps. But this is a combination BB and Pellet gun and as far as BB rifles goes 750 fps is a good speed for a BB. This is about as fast as they can possibly go. I own 2 of these and find them very entertaining to shoot for fun.
The 620 is a 4.5mm or .177 caliber pellet rifle and is rated around 450 FPS.
320 in a pellet gun is average. there are a few that have a higher FPS, but anything that fires between 300 - 400 FPS is normal for a C02 pistol. Rifles on the other hand currently are made to fire above 1000 FPS. The Crosman 1377C fires above 600 FPS but you have to pump it 10 times and it is a single shot pistol
All BB guns are alot less in (Strong) than Pellet guns. BB guns are luckey if they can attain 600 FPS (feet Per Second) Pellet guns & rifles can attain 1450 FPS. The fastest and most powerful BB gun I know of is the IZH Baikal Drozd that fires at 541 FPS. The Evanix AR6 Pellet rifles fires at 1450 FPS.
