I know a lot of predator hunters shoot the 223 cal. I was on gunbroker.com and noticed they have various manufactures and bullet weights available if there is anyone interested. I don't shoot a 223 so I can't tell you if the prices are good or not. The bottom line is if you need it, you gotta pay the price....if you can even find it!!
Just curious, if any one looks into it, let me know how the prices are.
