I picked up a jet several years ago with no model mark at all. Sometimes the factory does what the factory does...that is what makes this an interesting hobby.
...
Also, this required the .222" bullet that only Hornady ever produced, specifically for this cartridge. The 2210 Jet in 0.222", now discontinued. Sorry, for the poor pix. I still have a few boxes."
Reed Ammunition makes a .222 40gr. Soft Point bullet for the Jet, as well as loaded ammunition.
Best regards,
Never heard of Reed Ammunition... so, thanx for this. Hornady is, I guess, the only major manufacturer to make the .222".
