What presses and dies are you using and general equipment recommendations.

You can do every process on a Dillon 550b as a single stage if you want, do it all the time. It comes in handy building charge ladders.

Then you can run 500 rounds progressive in about 2 hours. It's all in the setup of the press. And if its correct, you can turn out very accurate ammo with low deviance. Most of my loads continually turn out sub-10 ES and SD's. If I do my part right, cloverleafs.

I use benchrest techniques for the AR but realize it ain't a benchrest rifle. If I can pop off 5 rounds just as soon as I get back on target and they are sub-moa, good enough for me. I don't need to shoot bugholes but the tighter the better.

I view my AR's as fighting tools first, then hunting, then paperpunchers. So for what I do, the Dillon 550b is excellent. Others may have different priorities.
