I wonder if AGT would sell you a kit. BBl. probe and mag. Wouldn't hurt to ask?
Oddly, I didn't want another .25, I wanted a .22 for my special slugs. or a .30 in a pinch. It is all I could find at the time. GRRRR! Now I'm glad I got the .25 as I have several molds and so far, every slug I have tested from them works and works well. From a choked bbl no ness. That's a new one on me. I've never had any much with choked bbl's and slug's always having to remove the chokes. But this one is ultra lightly choked.
The .30's aren't choked and I would have felt more confident in that cal. But it all seems to have worked out for the better. I am contacting the factory seeing if a .22 set up is possible for it.
