One benefit of ghost loading, other than the extra shot...it makes for a really, really fast follow up...to the point that I have “bump fired” it using slugs...at 20 yards, on a silhouette, the first shot aimed at belly-button level, the second shot smacks center-head, with a split down under .1 seconds. The first time it happened, I though I had a malfunction and it “doubled”...then I learned how to do it on demand.
Only works for your second shot, though...and is hit & miss on buckshot; has to be full-power loads, not reduced recoil.
