I've searched THR but don't see anything on the Gonic Arms BP rifles themselves (except one offered for sale a few years ago).

I've seen used GA rifles offered in very good condition (>95%) at very affordable (<$200) prices. I already know they used a slightly smaller diameter bullet than most, but I wonder if anyone here has one, and has kept it running on non-Gonic bullets.

I was thinking a Lee resizer in .501 might be the answer to useable fodder. If so, then the GA rifles would be a good deal. Any thoughts?

One of the sabot manufacturers is making sabots for the Gonic guns. BTW: Gonic is out of business.

There's also some conical bullet makers that offer custom sizing.
No Excuses Bullets specifically mentions Gonic:

Good info. Thanks! Even without the factory re-sizer, it looks like a Gonic can be fed and kept active.
