If money was no object, I would want a two component bullet like the Winchester FailSafe. It would do a better job of performing on both soft and hard targets than either FMJ, or HP. But it isn't available in .223, if that is your chosen weapon. Why not just stock up on some components so you can load what you need. No single load is going to do the best job in all situations.
Here is the specs for the .308 Winchester bullets and a link to their site. [url]www.winchester.com[/url]
