what would be the biggest animal you would be able to take down with an 5.56mm m4 carbine. I was thinking about buying on for an all-purpose type of weapon. Do you think you could take down a whitetale?
I shot a nice eight pointer with an AR-15 once. I believe the shot needs to be close and without major bone in the way. I got lucky and shattered the front leg (running toward me) and he collapsed, and I shot him twice more as he was trying to get up. After reflection, I decided not to do it again. I could very easily have just poked a hole in him and watched him run away. If you're mostly having standing shots where you can take your pick, then its not bad, but how often is that the case? Also, finding bullets that are designed for deer is harder. Most are varmint bullets. Having said all that, I was still impressed with what those rounds did to that deer. Deer was about 200 lbs live weight. Fairly heavy deer.
Yeah, I would say the 5.56 (.223) is marginal for whitetail. You would have to restrict yourself to near-perfect, standing, broadside shots. If you have enough discipline to limit yourself that way, then it's probably adequate.
It's a fine caliber for coyotes and hogs, and would probably be adequate for antelope.
I just got back from my elk trip to Colorado and must say that I learned quite a bit about hiking in that one trip. I researched all I could on the internet and thought I was prepared going out. For the most part I was but I want to pass on a few major things I learned that helped me drastically!
1. Pack light. I know this may sound like common sense but believe me. After reading everyone's advice on what you need to pack, chances are your pack will end up weighing more...
