The Crossman 760 Pumpmaster, It's Powerful, Safe and works like a real gun
This BB gun was made by WHO?
600 FPS - Pellet 625 FPS - BB
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.
Manufactures do not publish the distance that air guns fire they just say several hundred yards to be safe.
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.
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.
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.
PSI: It depends on how many times you pump the forearm. But Crosman says to never pump it more than 10 times. The 760 is rated at 625 FPS with a BB and 600 FPS with a pellet.
Go to the link below, and click on "customer care." I believe Crosman still repairs these rifles.
These rifles are very similar. Their are several variations of both rifles. Basically it came down to the shots that could be stored ( BB's) the original 760 only shot BB's and held 180 BB's. later versions could also shoot .177 pellets. The Pump Master had an 18 shot BB mag and a 5 shot .177 pellet mag
No- and it would be very dangerous to try. Pellet guns and airsoft are two very different things.
