Typically, the CasePro is used for straight walled semi-auto pistol brass. (.38 Super most likely)

But I have heard that it is possible to get die plates for .223 .

Reading this reloading section, it seems like a lot of guys here toss their .223 brass when the primer pockets get loose.

I am wondering if roll sizing it would re-tighten the primer pockets???

And in case you guys have no idea what I am talking about, here is a CasePro that has been motorized and is being fed by a Dillon casefeeder:



Here is another picture:



Amd here is a video:




I just figure if some guys are going through an annealing process to increase the life of their .223 brass, they might also be using a roll sizer too.

Just because you can buy something doesnt always mean its a good idea.  I dont think that it would tighten the primer pockets on 223.  The case web is actually pretty stout on the bottom end and because its so small, I dont think it would move much, if at all.  Most case failures on 223 are neck splits and occasional case separation, with primer pockets generally being the least of my concern.

A roll sizer is used to remove bulges (think Glock bulge) to make it feed 100% reliably in a pistol that has a tight chamber.
