A bb is a .177 caliber a 22 cal is bigger than a bb . the 22 cal pellets can weigh any where from 14.3 to 33.96 grains in the diabolo shape for a airguns , slugs can weigh even more . There is a big difference in a .177 cal and a 22 cal . A bb size or .177 cal lead pellet can weigh up to 16.20 grains . Any caliber bigger than a .177 cal is not called a bb. A hard round bb is not used in a rifled barrel air gun . Night hunting with a air rifle is not legal where I live so no night photos unless I go to the next state over and that's a once a year trip . I never take photos of anything I kill ,not even deer but I will try to take some this year of coyotes and post them to your name . I don't know anyone that takes photos of dead coyotes its like taking a photo of dead squirrels . Its not like they have racks on them to measure like you would on a deer . You don't mount them as far as I know anyways . I can see people taking photos of deer and fish but a coyote ? But if that's what your into I'll take a few pics for you . Just so you know airguns are legal to use to kill deer in my state 35 cal or bigger . When you read that the airgun is a 22 cal and produces 30 fpe at almost 1,000fps calling it a bb gun just makes you look stupid . Air guns have come a long way in the past 10 years and every year they are getting even more powerful and are used for hunting all sizes of animals from squirrels to a south Africa black wildebeest using a 357 cal and bigger . Here is a video of a 30 cal air gun with a night scope just to give you a idea what a airgun can do to a coyote and no a 30 cal is not a bb gun either .
