They don't exist.
My options are as follows
1) Buy a 30-30 extractor from Numrich and have material added to work on a Hornet. $17 delivered, plus the labor
2) Mail order a fabricated blank extractor and have it fitted for a Hornet locally. $50 delivered plus the labor
3) Buy the 30-30 (or other 219/220)( extractor and have the gun rechambered.
4) Part the gun out
5) Carry a cleaning rod, and hope one day to trip across an extractor or a rusted out Hornet barrel
I have $100 into the gun/scope, it has no sentimental value, but I would like to shoot it. as well as hunt with it.
Thoughts.
