There are 12 versions of the Crosman 760. Which one do you want.... See the link below
The Crossman 760 Pumpmaster, It's Powerful, Safe and works like a real gun
Manufactures do not publish the distance that air guns fire they just say several hundred yards to be safe.
First of all the 760 Pumpmaster can shoot any brand of BB's without any harm. But if you want Copperhead then I suggest you look at any sporting goods store. Like Walmart or Kmart. If you can not locate them then I suggest looking Online at Pyramydair they are the largest air gun store online.
Definetly the pump master. It is a multi pump gun so the fps depends on the number of pumps.
it depends on the model .22, in most cases the .22 will be more accurate because of the superior rifling in the barrel
Go to (The link below ) and find your parts and owners manual for your gun or rifle. Crosman keeps a web page for older airguns. They also have a list of service centers
The 760 is not designed for rodent control. It was designed for simple back yard target shooting. You may be able to kill the snake but it most likely would take several shots.
This BB gun was made by WHO?
Yes, but I would use Pellets not BB's in the rifle. Pellets are more accurate and deform on impact. BB's are not as accurate and do not deform on impact.
There are several different versions of the 760. See the Crosman link below. And select your model from the owners list. Then read section on Loading and unloading the BB rifle. This may help.
If you are asking about a pumpmaster made by Crosman then see the related link. There you will find at the bottom of the page a section called "download a manual" that will take you to all the Crosman owners manuals.
