Dimensionally or ballistically?

The 22 W.R.F. is an "old timer" cartridge compared to the 22 WMR. It was invented by Winchester in the year 1890 (specifically for the Model 1890 Slide-action rifle, and adpoted for use in the Model 1885 Single Shot Rifle). In its original form, it was loaded with a 45-grain flat-nosed lead bullet and 7-grains of FFF black powder. The listed velocity was 1140 fps. In the late 1890s, Winchester began to offer it in a smokeless powder loading that duplicated the black powder ballastics. In recent years, both Winchester and CCI manufacture it in both a 45-grain lead and 40-grain JHP loading. The 40-grain JHP is in the 1350 fps range.

The 22 WMR was invented by Winchester in 1959, and it is a relatively hot cartridge as compared to the older 22 W.R.F. Winchester listed it at 2000 fps with a 40-grain JHP.

The 22 W.R.F. can be used in any firearm so chambered, and in any firearm chambered for the 22 W.M.R., as dimensionally, it is the same diameter, but is .10" shorter. It is essentially the same thing as shooting a 22 Short in a 22 Long Rifle chambered gun. On the flip side, you can not shoot 22 WMR ammo in a gun originally made and chambered for 22 W.R.F. (or 22 Remington Special, which was Remington's version of the 22 W.R.F.).

The mag round has about 70% percent more power with the same bullet and a bigger shell case. The WRF muzzle velocity is what the WMR has at 100 yards. The WRF shoots flat to 60 yards and the WMR shoots flat to around 125 yards. Hope this helps. BTW, you need one of both Mike

I would wager that upwards of 90% of the milder 22 WRF rounds bought today are used in 22 WMR guns as small game gatherers. The milder round often has a lead bullet, and doesn't rip edible game to shreds like the Maggie often does. This is an excellent use for it, BTW.
