If the Owners instructions say BB's or Pellets can be used it would be OK. But IF the Owners manual says Pellets. Then NEVER use BB's in a pellet gun. Oh they will work. But you will ruin the rifling in the pellet gun or rifle.
Here is why. Good pellet guns have rifling in the barrel. (Little groves) that make the pellet spin as it is fired. Pellets have a soft skirt on the end that catches the air and conforms to these groves. This gives the pellet a spinning effect and adds to accuracy of the pellet.
BB guns have a smooth bore barrel ( Like a straw) the BB is hard and tumbles down the barrel and is not as accurate as pellets. If a BB is used in the Pellet barrel it slowly destroys the grooves in the rifled barrel. It also leaves residue from the copper in the barrel.
I've seen several good air rifles that have been ruined by the owner forcing it to shoot BB.
It's a poor idea to do this to a good air gun.
pellet=no bb's= 6mm plastic not copper.
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.
No recommended, Not designed for plastic BB's.
An air RIFLE that shoots pellets through a rifled barrel will leave identifying marks on a fired pellet. A smoothbore air GUN that shoots BBs usually will not.
Not recommended unless the owner's manual says so.
It's designed as a pellet rifle. Forcing it to fire BBs will ruin the rifling in the barrel. Rendering it much less accurate, It's a good way to ruin a pellet rifle.
If you are referring to casings like bullet casings after the bullet has been discharged, then the answer is "No." The entire Pellet is discharged from the gun when it is fired.
It would be 350fps which means that the BBs fired from the gun travel 350 feet per second.
FPS is the abbreviation for "Feet per second". Used to state how fast a pellet travels when first fired.
There are several BB/Pellet gun models on the market that have smooth bore. If your model is designed for both BBs and Pellets then you you can shoot both.
Depending on the exact model, when and where fired, you could lose some hearing.
Are you talking about an airgun pellet? If so, then hitting the sheet with force will deform the pellet. If it's a air-soft plastic pellet it will most likely shatter or at least crack or chip the pellet. Never reuse a pellet after it has been fired. It may damage the gun.
