My dad owns a shotgun and 22 I want to buy say 10-20 rounds of each kind. So with shotgun there is tiny pellets that spray , a slightly bigger pellets like 7 or something , one with 3 pellets and a whole slug. so buckshot is best for home defence? 22- is there hollow point regular 22 ??? So i should get buckshot and birdshot for pests and 22 hyper velocity? This is only a single shot shotgun and bolt single 22 atm Im getting other guns but it takes a month or so to process.
