Hi all,

I don’t have much experience with rimfire rifles, but I’m curious to know if there is a significant increase in performance of the .22 WMR over the .22 LR? What is the difference in trajectory between the two, and what is the effective working distance of each? Also, can I shoot a .22 LR round out of a rifle chambered for .22 WMR?

Thanks.

You can shoot a .22LR out of a .22 WMR, but its not a good idea. .22LR brass is very thin and you can split the case or blow the head off the case and get a lot of hot gases blown back in your face.

.22 WMR is about twice the speed of .22LR. .22LR is effective to about 75 yards, and 22 WMR is effective to about 125 yards or a little better.

Ken and Mat are both giving you good info. Never shoot ammo that is not chambered for the firearm your using. Injury and even death can result. Every modern firearm sold today has the correct cartridge to be used in it stamped on the barrel.

Take a look at these two articles.

http://en.wikipedia.org/wiki/.22_Long_Rifle

http://en.wikipedia.org/wiki/.22_WMR

Here's a good article on the 22 WMR by Chuck Hawks.

Here's his take on the 22 long rifle.

These will give you some insight to these fine rimfires.

last ? first ....... do not fire a lr in a gun chambered for WMR

The magnum far exceeds the lr in killing power ( performs closer to 22 hornet ). Trajectory ..... sight @ 50 yards magnum will shoot almost 3 inches flater @ 100 . Working distance will depend on the game hunted and your abilities !

The safe part first. "Don't fire" a cartridge that your firearm is not chambered for. Even "if it is possible?"!

22 magnum is as good as the 22 Hornet for most. NOT RE-LOADABLE and kinda expensive is the only downside that I see.

I know two rifles and one revolver that shoot very well.

Price of ammo would would make me select another option.

. NOT RE-LOADABLE

That's kind of the beauty part the way I operate. My centerfire rifles tend to stay in a state of flux. At any given time I may or may not have ammo reloaded or be zeroed for whatever ammo I might have. Might not even have sights or a scope on there.

My .22 Magnum is always loaded, always leaning by the back door, always sighted in.

I just caught ammo on sale for $9/50 rounds, you can't hardly buy jacketed .22 bullets for that anymore.

I shoot them both

The .22 Magnum is what I prefer for groundhogs around here instead of a centerfire because of close neighbors The .22 l.r. is a better choice for plinking and within its limitations is just fine. All the best...

The .22 WMR is a fine round but is no way the equal of a .22 Hornet. It really very nicely splits the difference between the .22 LR and the Hornet, with 40 grain bullets it is about 500-600 fps faster than LRs and about 600-700 fps below the standard factory load of the Hornet. The Hornet can be loaded with a 55 grain bullet a bit faster than the 30 grain loads from the .22 WMR.
The big advantages of the .22 WMR, as I see it, is that it is "enough gun" for many applications where the .22 LR may not be, it makes less noise than a Hornet, it is available in many of the same light and inexpensive rifles as the .22 LR and you don't have to spend time reloading or even pick up the brass. Yes the ammo is a lot more costly than .22 LRs but I don't "plink" with my mags and for hunting the magnum is a lot cheaper than any shotgun shell and no one complains about those, nor is it true that you can reload a Hornet for less, unless you shoot home cast bullets in your Hornet.
For many years the .22 WMR was handicapped by limited ammo choices, if your rifle didn't happen to like 40 grain bullets from CCI or Winchester, too bad, that was all you could get. Today there is almost a bewildering array of ammo to choose from and that greatly improves the odds of finding that one load which drives tacks from your rifle. The least expensive but still very good ammo I've found is the Fiocchi brand from Grafs. The Winchester "Dynapoint" is cheaper but terribly inaccurate in my two rifles and is the only brand of ammo which won't function in my AMT Automag pistol.

I think Ken K pretty much hit the nail on the head with his comment "your intended purpose should dictate your choice". The 22 WMR is much more powerful than the high speed or even hyper velocity 22 long rifle rounds. Most 22 WMR loads produce more energy at 100 yards than high speed long rifles do at the muzzle. They have a much flatter trajectory as well. Even when shooting small animals within 22 long rifle range (say 75 yards or so) the WMR will smack them much harder because of it's higher foot pounds of energy. The down side of course is the cost of the ammo. Comparing on sale prices of 22 long rifle vs WMR ammo the price differential is usually 6 to 8 times. Most of the folks I know who shoot WMR (myself included) shoot most of their WMR ammo either for shooting critters or for sighting in. I typically shoot a few hundred rounds of WMR a year as opposed to several thousand rounds of long rifles. Of course I have only one WMR (a Marlin heavy barrel rifle) as opposed to a bunch of regular 22 rifles and handguns. For targets, plinking, and short range hunting of smaller critters a nice 22 rifle is tough to beat. The WMR is a better choice if you need the extra range and power it provides.

I am finding the .22 WMR to be my favorite handgun round since acquiring an old AMT automag ll. I get 1700-1800fps from 30 grain loads, 1400-1500 with 40 grains and 1200-1300 with 50 grain bullets. That is faster from a 6" barrel than any .22 LR from a rifle and the AMT has the accuracy to make use of the speed. Ammo is a bit expensive for "plinking" but I just never was into spewing bullets just for the heck of it and .22 WMR costs less than JHP handloads from the .357.

Coyote Joe beat me to it......it seems a lot of folk sorta struggle to justify the round in a rifle.....so, to look at it from another angle when comparing the LR to the WMR, the WMR gives you LR rifle performance (or better) out of a handgun....out of a rifle it's even better, so, how can this be a bad thing at current $10/bx prices?.....Sure, it's not reloadable, but only a small percentage of shooters reload, and it's MUCH cheaper than any centerfire smallbore cartridge. I reload, only own a WMR handgun (Ruger SA), and don't shoot the cartridge all that much, but boy howdy am I glad it's there when I want it.....

I just acquired a Ruger Single Six, 6.5" barrel, blued, adjustable sights. I can't even begin to describe how much more nuts the .22 WMR has in this pistol. I am so used to shooting cotton tails with a .22 LR from many different handguns and rifles, the round is okay. I do have a Ruger 77/22 .22 WMR, and that is a coyote destroying combo, and way cheaper to operate than my .204 Ruger. My point is that today my Single Six did an amazing job on 4 cotton tails.

I teach women shooters

And I wholeheartedly promote the 22 Magnum over all the other cartridges for wandering the woods with. I use the 22 Magnum and the 45 Colt for practically everything, but the 22 Mag. will kill wildhogs effectively, along with lots of other smaller and less tough things, but I recommend a nine ounce Bearspray for BigBadBears

Agreed, I love the 22mag. Can't shoot it enough !!

I use my 22 mags as hunters. In that role they are superior to 22 lr in every way. With the variety of ammo available I can tailor its use from fmj's for paper thru sp's for edible game and use the 30 gr hp's to explode varmits. Try that with a 22 lr. Most of the comparisons on cost seem to compare the cheapest bulk lr to the mag. Its only twice the expense of the good lr ammo nd well worth it when you need the added power.

It's a bit expensive for plinking but I really don't waste ammo of any caliber and for hunting the cost is right in there with the cheaper shotgun shells.

I love the .22MAG. Many a pesky critter has died in my yard. Many Boy Scouts have completed their merit badges with my rifle. Hard to find ammo right now so the rifle pretty much sits there.

If you really wan to stir the pot compare the .17 to .22MAG. I chose the .22 but the .17 has ammo at local gun store and there is no .22 of any kind.
