AR's on deer
Good for the youngsters and their fist deer!
And I will fully admit that bamaboy at age 11 took his first two with Mark X Mini Mauser in .223, with Federal bonded bullets, (62 gr tac-load) from support, at sub 100 yds, me coaching at his ear, and a bunch of practice and skull sessions about where to hit'em. He could have done just as well with an AR so chambered, but we did not have one at the time. We moved to the .243 bolt rifle pretty quickly, now I have to arm wrestle him for the .308.
But regards AR's in .223, it seems about every season now, I'll run up on somebody that has lost a deer shooting at it with an AR or a Mini14 (sometimes an economy bolt rifle). In the course of listening to their lament, which they usually are voluteering freely, their seems to be a common thread(s).
1) they equate getting a shot and losing a deer as some sort of accomplishment, ie, at least they were "good enough" to get a shot. I hear the same thing from some bow hunters. (no flame intended)
2) Their hunting experience and overall savvy is a bit low, shot too quickly, shot in bad light, bad angle, did not track or work to recover the deer very long, shot at a running animal, etc
3) When asked, they will have no good idea of the type of projectile they used in .223, other than, perhaps, the bullet weight, or more typically, just the mfg and that it was a "soft point" or lead tip, or some other broad description. And there are .223 rounds that are just not suitable for deer.
Now, items 1 & 2 above can occur irregardless of what the culprit is shooting. So too, item 3, but in the larger "deer calibers" there is a lot more room for error. Yes, a gut shot is a gut shot, but mix up your bullet weights from about .25 cal and up, and the likelihood of having a slug fail to penetrate to vitals drops significantly, on an angling or shoulder shot.
Not so the .223. And with the absolute rage of the AR/223 in full cry, I hear more and more about guys using one on deer where legal. I write all this to encourage all AR/.223 shooters to pay attention to their ammo selection, and pick their shots carefully.
But if your on this forum, your likely enough of an enthusiast to know all this already.
