Ok, I rest my case. It's now my firm conviction that I should get an AR (if I'm to even get one at all) in 5.56 as a prepper weapon that can also be a rat-killer, fun gun and casual plinker too. 5.56 ammo is so cheap and plenty. I should just have other guns for hunting deer altogether. Some people here feel confident for 5.56/.233 on deer but I still don't feel it's right for ME. I hate to cruelly wound animals. I've seen coyote videos with guys shooting 5.56/.233 at coyotes and the poor dogs spin and yelp in pain for a long time. But I digress. I still think DB looks nice for the modest retail price. I'll sleep on it.
