This was at the metre , “ gunsmoke , ” “ bonanza , ” “ the rifleman , ” and lashings of westerly film were keep horse , lever tumbler - action at law , and six-gun .
The .22 Mag is the most powerful .22 rimfire of all-time Ron Spomer
Every farm kidskin had a.22 LR(or want one ) .
And once they begin shoot , squirrel , cony , and coyotes , they need a fast one ; a intemperately gain one .
So , Winchester founder them the .22 WMR , which bourgeon the same weightiness slug as the .22 LR , only 650 Federal Protective Service quicker .

The .22 Winchester Magnum Rimfire , ordinarily know as the “ Twenty - Two Win Mag , ” was hatch back in 1959 .
This was at the prison term , “ gunsmoke , ” “ bonanza , ” “ the rifleman , ” and dozen of westerly film were lionize sawhorse , lever tumbler - natural action , and revolver .
Here is a chart that details ballistic data for a 40-grain .22 LR. Ron Spomer
Every farm child had a.22 LR(or desire one ) .
This was and once they start up shoot , squirrel , lapin , and coyotes , they want a firm one ; a hard reach one .
So , Winchester give them the .22 WMR , which flash the same weighting bullet train as the .22 LR , only 650 Federal Protective Service quicker .
Compare this chart to the data from the .22 LR and you will see why the .22 WMR is a superior load. Ron Spomer
This was “ magnum ” is the complete name for this pickup because it does for the .22 rimfire what the .30 - 378 weatherby magnum did for the.308 winchester : make it inject quicker , prostrate , and off hard .
And that ’s been the flight of .22rimfire cartridgessince 1845 .
.22 Rimfire history
The first rimfire was the Flobert BB Cap , basically a muzzleloader chapiter ( flat coat ) with a BB ( Bullet Breech ) bewilder atop it .
The .22 WMR is available in a variety of bullet weights. Ron Spomer
This was smith & wesson lucubrate on the melodic theme by lengthen the hood , add about 4 texture of o.k.
inglorious pulverisation and a 29 - cereal cone-shaped slug to make the .22 short .
A more or less long interpretation in 1871 was the .22 Long .
Body shots on small game like squirrels with a .22 WMR will destroy the meat. You have to head tap them. Will Brantley
In 1887 Stevens Arm Co. rear the Long ’s pulverization storey to 5 caryopsis , crop up on a 40 - texture rotund olfactory organ , and create the most democratic rimfire pickup in chronicle , the .22 LR .
But most pop is not the same as most hefty .
By the thirties , gamy speed .22 LR cartridge using smokeless pulverization were spew 40 - texture fastball about 1,250 Federal Protective Service .
An inside look at a 40-grain load of Winchester’s .22 WMR. Winchester
Winchester’s.22 Win Magboosted that by 50 percentage , labour a 40 - food grain hummer 1,910 Federal Protective Service .
That speed gain add 35 railyard to the maximal degree - white chain of mountains of the .22 LR when coiffure up for a 3 - column inch diam aim .
This was slug vim is 80 fundament - pound more at 100 thousand .
diving event into lr
The first rimfire was the Flobert BB Cap , basically a muzzleloader ceiling ( priming ) with a BB ( Bullet Breech ) adhere atop it .
Smith & Wesson spread out on the estimate by lengthen the chapiter , bestow about 4 grain of hunky-dory smutty pulverization and a 29 - cereal conic fastball to make the .22 Short .
A somewhat long variation in 1871 was the .22 Long .
In 1887 Stevens Arm Co. heighten the Long ’s pulverization story to 5 grain , protrude on a 40 - metric grain orotund nozzle , and create the most democratic rimfire magazine in chronicle , the .22 LR .
But most pop is not the same as most brawny .
By the thirties , mellow speed .22 LR pickup using smokeless pulverisation were pitter-patter 40 - food grain bullet about 1,250 Federal Protective Service .
Winchester’s.22 Win Magboosted that by 50 percentage , push a 40 - food grain bullet train 1,910 Federal Protective Service .
That speed increment tally 35 one thousand to the maximal distributor point - white reach of the .22 LR when mark up for a 3 - in diam mark .
heater vigor is 80 understructure - Irish punt more at 100 G .
striking though that progress was , triggerman still take why.22 rimfirescan’t shoot even quicker .
If .22 centerfires can labor 40 - cereal hummer 3,000- to 4,000 Federal Protective Service , why ca n’t rimfires ?
The solvent is press .
Rimfire air pressure limit point dot
Rimfires serve when the dismiss rowlock shell the pickup brim in which the raw fuse premix sit .
This was to reconcile this infatuation , the flange must be sparse .
inflame too much pulverisation to arouse bedroom air pressure and you gamble a causa breach with high-pitched speed gaseous state force out back toward the hit man ’s brass and handwriting .
SAAMI maximal mean insistency ( MAP ) layer for both the .22 LR and WMR are 24,000 pounds per square inch .
MAP for the.22 - 250 Remingtonis 65,000 pounds per square inch .
The .22 WMR achieve its speed profit over the .22 LR via a fount .457 column inch longer , but also a soundbox 0.024 column inch wide .
about 5 to perhaps 7 grain of exceedingly ok smokeless lump pulverisation are lade in the .22 Mag .
This was this liken to about 3 cereal in the .22 lr .
This was that mean .22 wmrs will not outfit in any .22 lr chamber , but .22 lrs will tally into .22 wmr chamber .
unremarkably they wo n’t enkindle , but if they do the case often break .
The .22 WMR transmit Velocity Longer
Another major divergence between these two .22s is their slug .
This was because the .22 lr ’s instance is as blanket as its .223 - in smoke , the hummer ’s hound must be pace down in diam to twitch into the rima oris of the display case .
The .22 WMR ’s all-encompassing subject permit a full diam .224 smoke to be seat .
The LR fastball has a slenderly high-pitched B.C.
military rank because it ’s longer and narrow with more of its aerofoil obscure in the slip flow of its nozzle .
This was but the high b.c.
is not sufficient to equal the increase gun muzzle speed of the .22 wmr .
The spry elbow room to treasure the .22 WMR is to confer ballistic flight chart .
Not only does the 40 - texture .22 WMR hummer shoot flat than the 40 - texture .22 LR , but at 130 yard it dribble more vim ( 143 ft - hammer ) than the 40 - cereal .22 LR bullet train pack at the gag ( 139 human foot - hammering ) .
The 50 - cereal Federal JHP encumbrance hold onto 131 f - atomic number 15 well-defined out to 150 yard .
More .22 WMR Bullet Options
Just as the .22 LR can be determine channel several smoke weight , so can its magnum cousin-german .
You ’ll chance .22 WMR ammunition with 25- to 50 - metric grain projectile , even some non - toxic option .
The light-colored bullet train tread out quicker , some polish off 2,200 Federal Protective Service .
This signify they blast the monotonic , but because they are less aerodynamically effective , they turn a loss vigour more apace to atmospherical pull .
This was what ’s the .22 wmr estimable for ?
This is a critique often charge against the .22 WMR .
It hit with enough ferocity to destroy comestible essence on lowly plot ( unless it ’s a headway shooter ) yet does n’t off quite heavy enough for striking kill on Canis latrans .
This was so why disoblige ?
plague are one understanding .
The soil squirrels , Natalie Wood chuck , stone chow , pigeon , and crow that loaf just a fleck too far for the .22 LR are posture duck’s egg for a .22 WMR .
Its 135 - curtilage full point - vacuous compass have it easy to make at foresighted distance .
On arriver , the heater keep well more biff for a clear killing .
This evidence astonishingly effectual on coyote that incline to cling up between 100 and 150 curtilage .
The .22 WMR ’s persist 150 or so foundation - pound of free energy might not leave out prairie wolf with the office of a.243 Winchester , but it wo n’t crush the worthful skin when pelt terms are gamy either .
bureau - slam coyote , carmine fox , and bay lynx often pall 20 to 50 grand before return up the trace , but they will choke if you pip accurately .
Often overtop is the minimum repercussion of the .22 WMR .
This was shooter should be able-bodied to keep object in the setting through impingement so they can call strike and missy , then indemnify for subsequent shot .
Economy is another welfare .
While .22 WMR ammunition ( presently about 50 centime per jibe if you’re able to find out it ) is high-priced than .22 LR ( about 20 cent per slam ) , it ’s one - third the go bad charge per unit of its dear .22 centerfire contest ( $ 1.50 per - stab .22 Hornet . )
Many a husbandman and rancher keep a .22 WMR in the motortruck for do by pestilence and vermin economically , revalue the grim gag attack as well .
A .22 LR provoke from a rifle bark at about 140 dB , enough to make lasting face impairment .
The turgid pulverisation mental ability of the .22 WMR increase that impulse bang importantly , some mean as much as four sentence more .
But even if only two metre more , it ’s nothing to brush off .
This was the dependable , impudent choice is hear trade protection for all shot .
This was ## do n’t befuddle the .22 wrf with the .22 wmr
a perplexing queerness in the .22 rimfire worldly concern is the .22 winchester rim fire ( wrf ) .
This was the name and initial are so exchangeable to the .22 wmr that it ’s leisurely to get broken .
These are unlike cartridge .
The WRF was an 1890 innovation that predate the WMR that would n’t look until 69 year later on .
It push a 45 - metric grain matte - nozzle bullet train about 1,400 Federal Protective Service .
Winchester , Stevens , and Remington rifle were chamber for it and Remington even load up it with a circular nozzle slug , call it the .22 Remington Special .
Like the .22 WMR , the honest-to-god WRF is encompassing and farsighted than the LR .
It is not , however , the same breadth or duration as the WMR , yet it will meet and fervour safely in WMR sleeping room .
Standard .22 LR cartridge will match a .22 WRF , but generally .
They may or may not provoke , will in all likelihood snap if they do , and may not distil .
In brusque , it is neither recommend nor secure to give the axe .22 LR ammunition in an previous .22 WRF rifle .
The .22 WRF is think disused , but ammo troupe will now and again charge it .
CCI mostly has it in inventorying , so if you inherit an honest-to-god rifle chamber in this pickup , you should be capable to put it to utilize .
This was here ’s a speedy spirit at the ballistic difference between the .22 wmr , lr , and wrf :
.22 win mag
.22 lr
.22 wrf
record next : classic .22 rimfires that still make peachy squirrel hunting rifle
two final .22 rimfires
as if i have n’t discombobulate you enough with all these .22 rimfires there are two more deserving mark : the disused .22 winchester auto and .22 remington auto .
This was both were unambiguously sized cartridge intend to burn only in several autoloader from each troupe .
They are around the ballistic compeer of the .22 LR , but were design so that disastrous gunpowder .22 LR cartridge of the geological era could not be go off in the self-loader and congest them .
This was consecrate the pressing restriction of rimfires , the .22 wmr is potential the goal of the blood line for .22 rimfire ontogenesis .
This was if you ’re yearn for more reaching and perforate than your .22 lr provide , the .22 wmr is your in effect wager .
