They are both the same size. .177
A .177 caliber air rifle has very little recoil.
No it is not possible (in the USA) Crosman only makes the Phantom in a 177 Caliber. However I believe the Phantom .22 is made for Canada and Yes it will kill a bird.
Yes. ANY caliber gun can actually kill a person, but some calibers are more efficient at doing it.
Typically BBs are .177 caliber. BB stains for ball bearing, which can be ANY size, those popular for shooting are 177.
Most BB are .177 caliber but there are a few that are .175 caliber.
As long as the pellet is .177 Cal then any .177 caliber pellet will work in your .177 Gamo.
You need to consult your owner's manual. Some BB guns can shoot pellets, but some cannot.
Yeah eventually from lead poisioning! Not a good idea. Coyotes are to big for an air rifle.
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.
Which model?
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.
