I have shot many 223 bullets down range in prairie dog towns . We desire the best accuracy we can get. I started with 335 but went looking for something else because

It was so dirty. I have shot several 8# jugs of Accurate 2230 and am very happy with it. If memory serves me Ithink 24 to 25 grains under a 50 or 55 gr bullet was the best.

It worked in all of the rifles I have had .( Cooper, savage, Herters, Remington )
