We've killed a few with 50 and 55 gr NBT's in AR's, I'm not sure why people think they need a magical bullet.
That said I've also used Barnes TSX in 55 and 62 grs and they do work fine. This 64 gr bonded bullet will work too I'm pretty sure.
50 and 55 NBTs I wouldn't trust for penetration in some shots on some animals. That said if you konw your bullet and how to place it all will be fine. Its how I kill most hogs with subs in a 22 lr with a can... where most folks think you can't kill a pig without a big gun. Heck even the ones over 200 and over 250 every now and then still die...
