Not Likely. That is too slow. You would need around 600FPS.
Yes, there are several pre-charged, and break action pellet rifles that can more then kill a deer. They even use them to kill Wolf and Coyotes. However, you'd need a rifle with 16+ foot pounds to reliably kill large animals.
no pellet guns can not because they are not powerful to penetrait skin and zombies tougher to kill then humans and you can not kill a human with a pellet gun *** New Answer *** The above answer is incorrect. Most pellet guns can penetrate the skin, they may not kill you but it will hurt. If you have a .257 or larger PCP Airgun that produces a higher fpe then yes you could kill a Zombie. People need to stop looking at Airguns as toys, they are not toys and the higher caliber airguns can kill. So Please practice Safety!!! Oh yeah, you need to shoot the Zombie in the head so I would use a 35cal PCP with a 3500psi tank with the valve set to 950psi burst, or a MAC35 with the cartridge set to 4500psi. :-)
After the bird is dispatched, yes. It is a good idea to hang the bird to drain the remaining blood.
Possible- depending on the pellet gun. I hunt smaller animals (squirrels) with a Sheridan 5mm rifle. It WILL kill a squirrel at 45 yards. However, a squirrel and a turkey are 2 very different animals. To kill a turkey cleanly, it would have to be a head shot- and turkeys are VERY skittish animals. You also need to check if it would be LEGAL to kill a turkey with a pellet gun in YOUR state (assuming we are talking about a wild turkey) The game laws are different for each state.
Parakeets CAN eat many things but clay they should not eat.
You need to state "MADE by Who" there are over 100 different companies that make pellet rifles.
Nope. Pellet guns are fairly safe to use.
I don't need, but I know it. The plat die pellet machine can be mainly classified into diesel-flat-die-pellet-mill and electric-flat-die-pellet-mill. More details can be searched in this website. http://www.buypelletmill.com/product/index.html
There are too many variables to be able to answer that. would need to know the size of the bullet and the type of lead.
You will need a .177 caliber cleaning rod to push the pellet back into the loading breech from the barrel.
You will need to contact a lawyer. To many variations in local and state laws for a cookie cutter answer.
