Re: What is needed to make .300 blackout from .223?
I've done it this way, only using the HF mini-chop saw instead of the drill press.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: matthias</div><div class="ubbcode-body">when i do it it goes like this
-remove ball\expander from sizing die
-run all brass through die making a second shoulder
-cut off brass with drill press that has a cut off wheel mounted horozontally
-put expander ball back in die and run brass through again
-trim , de bur , load
i take the expander out in the beginning because it makes less effort on the press handle and why size brass you are going to cut off in the next step?
so far i have done 500 cases this way and i have not burned out the cut off wheel yet. another thousand 556's showed up so i will be busy </div></div>
I also agree with this:

It is a very tedious process, and I'm not a lazy person, but damn. It takes a long time and it is so much easier to just buy 1000 pieces of converted LC brass.
