I have found many a laugh in watching a crow literally "Explode" whan tagged by a 50 Ballistic tip from one of my 220 Swifts. Most often, only the wings get to the ground, the rest just "floats off in the breeze" as another poster mentioned. Crows are smart. When they are shot at a lot, they learn how far out they have to perch to be relatively safe. One thing they don't realize is how much farther they need to be away on a very calm day. Then the Swift is dangerous to them out to 400+ yards. HA!! I was gopher hunting around Eckville Alberta some years ago, and the crows there were used to being poked at with 22 rimfires. They would feast on dead gophers as long as you were outside of 150 or so yards. I sure surprised a few of those with the 222, 22-250 and 220 Swift. One sure thing, we'll never run out of crows!
