 Rimfire - Wikipedia, the free encyclopedia
It is called a rimfire because, instead of the firing pin striking the primer cap at the center of the base of the cartridge to ignite it (as in a centerfire cartridge), the pin strikes the base's rim.
The next rimfire cartridge was the.22 Short, developed for Smith and Wesson's first revolver; it used a longer rimfire case and 4 grains (260 mg) of fl powder to fire a conical bullet.
While larger rimfire calibers were made, such as the.44 Henry and the.41 Remington, the larger calibers were quickly replaced by centerfire versions, and today the.22 caliber rimfires are all that survive of the early rimfires.

 Rimfire, West Virginia's Typical Mountaineer
When first organized, the Rimfire Scouts were sadly misjudged by some of the local people, who accused them of being a disreputable lot, banded together for the sole purpose of violating the game laws, cheating at "shootin'" matches, stealing hogs and various other crimes and misdemeanors.
Rimfire and his officers were the whole show, as at that time there were no movies, radios, or other form of entertainment and you could always count on a large attendance at the Scout Hall at their regular meetings.
Rimfire and all of his old cronies are long since gone to that happy hunting ground where we hope that streams and forests abound with fish and game to occupy their time.

 The Telegraph - News - 12/13/2003 - Site eyed by Olin for Rimfire plant has lost jobs   (Site not responding. Last check: 2007-11-07)
The community that is courting Olin Corp. to move its Rimfire munitions operation from East Alton has struggled with keeping its industry as much as anywhere else, said the head of the Oxford-Lafayette County (Miss.) Chamber of Commerce.
If Olin were to move Rimfire, a division of Winchester Manufacturing, to the Oxford area, it would move with it a significant portion of the 150 jobs at Rimfire and provide a boon to the area.
Olin told the union that the Rimfire production line had "severe profit margin erosion and market share loss in recent years," with the volume of loaded rounds sold hitting a 30-year low in 2002.

At one time rimfire cartridges were available in many bullet diameters up through the.56-56 Spencer, which appeared in the hands of Union forces at the battle of Antietam in September 1862.

She also said -- and Arbogast confirmed -- that none of the 150 former Rimfire workers were laid off.
If Rimfire continues to hire at its expected levels, Lafayette County -- recently named the fourth-best area for retirees by Kiplinger Magazine -- will have replaced 600 of the 800 manufacturing jobs it lost in 2002.

Leupold designates two models as Rimfire scopes that do not have adjustable objectives and have the parallax pre-set at 60 yards from the factory.
The E.F.R.s have adjustable objectives that have the ability to focus at a very close range, thus being parallax free at closer ranges for airguns or rimfires.
Airguns require scopes to be extra heavy duty because of the reverse recoil (all Leupold scopes are airgun compatible).

I usually test rimfires for accuracy at 50 yards, but since nearly all of the Sako centerfires I've used over the years have been capable of MOA accuracy, I wanted to see how the Finnfire Hunter would perform at 100 yards.
