I dont think you have to worry about being to graphic on here, we are hunters not bird watchers. I have 2 guns built just for crow hunting I use a 223AI and And a 22-250AI The 250AI is pushing a 50G vmax at 4085fps and I can diffently tell what side of the center of the brestbone I hit with it. The majority of the carnage will propel to the opposite side. These guns are mainly for 300 yards and under. I have a 220 swift with a 1-8 twist barrel that I am fine tuning to attempt a 500 yard shot on a Black corvid. I plan on using a foxpro caller and my crow decoy (buster) to get the bird at exactly 500 yards. If your interested in a Remington 700 with a Remington custom shop barrelled 220 swift that has a .260 no turn neck give me a call 419 564 7727 Tony.
