Possibly. Fortunately air guns are something I know a lot about. First off get a chronograph and some accurate pellets that are more than 30 grains. Accuracy you want is about 3/4 of an inch and a good knowledge of their vitals. Most talon/falcon hunters in .25 make 25-28 ft.lbs at the muzzle depending on your gun. Check out the predator polymags, rapid expansion. For turkey stick to shotguns or bows, a dedicated turkey air rifle would be 50+ ft.lbs .25 cal or larger PCP air rifle using 43+ grain slugs. Your talon magnum/falcon magnum should only be used at 20 yards or less...
