Quoted:
I know its not the same thing, but I have been using my Adams Arms 5.45x39 AR-15 loaded with these Hornady 60 gr V-max rounds for hog hunting. I do find that it lacks in penetration. But on the smaller hogs (~100 lbs) its a 1 hit kill to the front half. Bigger boars I have not been able to bring down by myself consistently (even with multiple shots) but this may be due to poor shot placement by me. Just my 2 cents.
And of course as soon as I say this I bag another hog with this Hornady V-max 5.45. This was a very quick shot, as I could only see the hog run through a clearing of very dense foliage for a fraction of a second, but I was either lucky or that practice paid off and got a neck shot. Hog was DRT.
Did not stick around to recover the bullet, but did not see an exit wound and it looks like the pig was only about ~9 inches wide at that point.
