Best .223 bullet for deer?

[Larryjk]

Petey, Since you don't care what people think, why do you ask their opinion about a bullet? You are already shooting the Nosler 60 grain Partition which is about as heavy as 1x12 rifling will stabilize. Shoot for the heart. Find drawings of where the heart is from different views. Hope for the best. If they get away, so what! There are lots of deer and your boy needs the experience.
