Question about an old box of .22 ammo

As written on the box, it's the old 22 RF Winchester. It's longer and slightly more powerful than our current 22 Long Rifle rounds. As you can see, it actually has an inside lubricated bullet compared to our common Short, Long, and Long Rifle rounds. It is not usable (due to the case diameter and length) in a rifle or revolver marked for 22 Short, Long, or Long rifle. Reportedly, the round can be fired in a 22 Magnum rifle as the case dimensions are pretty much the same.

In my youth, I still saw boxes of these on the sporting goods and hardware store shelves. I've never fired the round though. The "H" on the headstamp stands for Mr. Henry, who was employed by Mr. Winchester in the development of his first lever action rifle... the Henry rifle.

Someone will probably correct me, but I think that Winchester developed the 22 RF Magnum from the 22 Winchester.

Older than dirt, I'd say

Thanks for all the info, Schuetze. Why do you suppose it says "model 1890" on the box?
I wonder if the model 1890 was the only rifle made at that time for .22 WRF .

.22WRF is still manufactured today, but is very rare in stores.
Winchester offers it in flatnose plated and CCI offers it in a JHP.

Introduced in the Winchester M1890 slide rifle, a variety of Winchester, Remington, and Stevens single-shot and repeater rifles were offered from 1890 onward, but new rifles are not made for this cartridge.
