Got one in the morning and one in the late afternoon with a Gamo Viper rifle, and a RWS Diana P5 Magnum pistol. The Viper`s shot was at 34 yard distance and the P5`s was at 13 yards. Both birds took a dirt nap immediately...no kicking, flapping or twitching.
Viper iswearing a Barska 3X12-50mm IR scope set at 10X and spitted out a .177 CPHP pellet. The Diana P5 just used the cheapy .177 Crosman Wadcutter.
