I had a couple LNL’s a pre and post EZ Ject. I really liked the idea of the half index until I used it loading 308. The combination I was using was tall enough I couldn’t set the bullet on the case mouth to seat, because it was not under the die when it finished the second half of the index, knocking the bullet off.
I had to put the bullet up into the die, raise the handle enough for it to finish the index and set the bullet into the case, then finish the stroke.
I am pretty sure you would be just fine with the .223 but I’d still get a Dillon. I had actually bought my first LNL because of how much better everyone claimed their powder measure worked with extruded powders and I had a lot of old long cut 3031. Unfortunately, I couldn’t tell their measure did any better than the Dillon.
If you were the one that started the what powder thread and are going progressive (any of them) do your self a favor and purchase spherical or ball powders.
