I've carried the AK a few times, but not taken a deer with it, no shots, no deer sighted. Sights are darn hard to see. A Tx dogleg mount and a scope will fix that, but I've not made the investment...yet.
What I have done is killed several with a Mini-30 and a Ruger 77mkII and the x39mm round. So has bamaboy. Load has been a 135 gr reload. Same results as a .30-30. Including one real whopper.
