Good news - my Compatto apparently loves Neilsen's 17.5 grain slug. The bad news is I have had 3 feeding issues while attempting to shoot my first 5-shot group. I can't figure out what is going on either. Just every other shot or so I can't move the bolt forward to cycle the next slug. I can't see what the slug is hanging on while trying to feed. I've mangled several slugs while getting things unjammed.
The Compatto uses the Daystate magazine - pic below, which is otherwise cycling pellets fine. My suspicion is the slug is rotating head down in the magazine while loading and hanging up in the breech opening somehow. Anybody experienced slug feeding issues with this style magazine?
