My daughter drew a cow tag this year and Im trying to decide what to have her shoot. .243 seems much too light to me but I know plenty of people who have had success in cows with .243s. My other daughter shot her mule deer with a .243 last year which blew through both scapulas and exited the far side. That said .243 seems plenty good for cows but curious on everyone elses thoughts. I can also borrow a 7-08 but my daughter already doesnt like the .243 recoil. Right now Im leaning toward having her shoot what shes most comfortable with (243 - she can consistently hit a soda can at 100 yards with it), and limit shots within 200 yards or so. Let me know what you think.
