I’m chasing concentricity with my reloads. These reloads are just 223 blasting ammo. Issue is I’m using mixed brass. If I was using consistent brand brass I would just go with a bushing die.
Here is what I’ve tried so far.
I started with pushing the expander ball instead of pulling. So I would full length resize the case with no expander in the die. Then on the next step I would put the expander back in and put it way down in the die so I could expand on the downstroke. Didn’t help. In fact, I didn’t really notice a change at all from just regular resizing with the expander ball.
Then I decided to try using a neck sizer die and then a body sizing die. Two separate operations. I dunno… I read about it on a reloading forum 15 years ago. This actually marginally improved concentricity though.
I’m concerned that a bushing die will be great for brand A brass, but not give the correct bullet tension for brand B brass. And for blasting ammo I’m not interested in sorting by brand. Is that something I should be worrying about?
Do you all know any other tricks to improve concentricity? Should I just buy a bushing die and be done with it?
Non-concentric cases are so ugly when they come out of the Giraud power trimmer.
