A .25 cal Beretta is capable of inflicting a serious wound and even a deadly one.
It was not designed for 25 cal ammunition.
The question can't be answered without knowing the exact 25 cal you are referring to.
25-50
17 mph
No, no air rifle has a capablitay to kill a deer. The maruader is a great gun but it can only kill up to a rabbit or mabye a fox. If you try to shoot a deer with that it will charge at you or it will just shake it off.
Very passably "Yes" with a head shot using hunting (hollow point) pellets

Yes it is possible. An air soft gun will not kill you but a pellet rifle is capable if killing a person. Pellet rifles come in several calibers. .177, .20, .22, .25, 9mm, 45 cal and 50 cal. The last 3 calibers are fired from a PCP pellet rifle. This rifle (PCP) uses a scuba tank to charge the rifle with 3000 psi of air. All of these pellets are capable of injury or death.
