I like the heavier .223 projectiles. The ones that are like big game bullets in miniature. The 70 grain Speer, 60 grain Nosler Partition, 64 grain Winchester, 75 grain Hornady. I have my AR loaded with 28, 70 grain Speers. I'm forever the optimist and I have a never say die attitude, but if I can't take out the threat with 28 .223 70 grain Speers, projectiles whose wound profile is very similar to and virtually indistinguishable from a 100 grain .243...then I guess I'll have to reload.
