Thread: Reducing ES - 223

Best combo I found with mine was 8208 over CCI 450's. Seemed to give decent ES and SD numbers with a wide range of bullets. But as gimp says, it's a pig. Getting a single digit SD (and sometimes a single digit ES) is pretty much automatic when using premium brass and a good scale in my bigger cartridges with almost any primer, powder, bullet combo. But it's never been a given in any of the the four factory 223's I've owned.

My T3X is now being rebarreled to 223ai with a trueflite barrel. It will be interesting to see if the improved case design and high end barrel makes any difference.
