You can't it's not designed to be a repeater.
If:It is close rangeYou use enough pumpsThe crow is standing perfectly stillYou are an excellent shotAnd you put it right through the crow's eye,Then yes, you can kill a crow with a Crosman Pumpmaster 760.
What caliber is your beretta ????
46x53 nado
.45 ACP
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.
wesson. .44 calibur.
I would refrain from using oil other than Crosman Pellgunoil on my 760. 3n1 and WD40 are not designed for air rifles and may actually damage the seals. Pellgunoil is designed for Air guns. Follow the recommended locations per the manual. (If you lost the manual Crosman.com has them online.) On your airguns, that use C02, put a drop of Pellgunoil on the end of the C02 bottle before you install it .This will lubricate the system from within
Only if the gun is designed for BB's. Some air rifles are designed to shoot either. Usually they are the multy pump design like the Crosman 760 or the Daisy 880, but air rifles will say right on the barrel that they are designed for .177 cal pellets or .22 caliber pellets and these rifles or guns should not use BB's. BB's will damage the rifling in the barrel.
He used a special kind of ammo called expanding bullets that is illegal in most countries. They're also called dumdum bullets. When dumdum bullets hit the target they expand inside the target, in this case inside the body, causing much more damage than normal bullets.
