Ive been looking at buying a rifle something in the .22 range, basically for small game. i have been very interested in .22WMR especially in the marlin brand. Is it possible to have a rifle that is chambered for .22LR and .22 magnum ammo?

the local range i use prohibits the use of magnum loads this is the reason for the question. (.22 magnum isnt allowed but for some reason .308 winchesters are allowed :mad: )

thanks for the help in advanced.

The chamber is different. I guess you could buy a single shot breakopen rifle with two barrels 22lr & 22mag, but then you might as well buy two different rifles. Just remember to tell your wife you've had one of them "forever".

:scrutiny: Wow I would think somebody that operates a range would know something about guns.

Thompson Center's Contender is about the only thing I could think of. I think the Encore has a conversion you can get, but the Contender is already set up to shoot rimfire. LOP and trigger will be the same with both, and if you purchase identical scopes, you should have a fairly easy to switch between rifle.

Now, you're probably realistically looking at spending at least $800 after scopes and the extra barrel, so like jmorris pointed out, you'll have as much invested as you would with two rifles. SC

Not only the chamber but the bores are different - 0.218" vs 0.224". The only guns I know of so chambered are Ruger pistols with different cylinders for each cartridge. They usually don`t shoot the 22lr very well because of a loose fit to the bore.

you would either have to get a switch cyl revolver, or switch bbl rifle.
such as a Sako or a majestic arms. the revolver from say taurus would be about 275 to 300 dollars. the other two rifles will cost you some shiiiny pennies!

Hi "Ol' Joe"...

E'scuse me, Suh. Your statement is one I must issue vivid disagreement with, Suh. It, in my humble Buckeye opinion, Suh, is lore, pure, simple, and roundly incorrect, and certainly should not be repeated - especially in the presence of people. I will make haste to forgive you your horrific lapse of discretion, Suh, but I shudder to imagine what must the people reading such rantings think of your mental state. Suh.

:D

I would take a 22 mag to that range and if they say you can't shoot it, then ask them what kind of energy it dishes out compared to a .38 Special.

Then, find another range because if they are so dumb they don't even know what a .22 mag is, then they probably are too dumb to enforce the right rules to keep you safe while at that range.

[reading Shawnee's post]

I'm not sure whether to take that as sarcasm or what. :scrutiny:

Both Single Six convertibles I've owned printed better groups with .22WMR than with .22LR. Whether that's due to a difference in bore size or other reasons I couldn't tell you.

snapsy, I had the same question a couple of years ago. I just decided to go with multiple rifles. I went cheap on the .22LR (Marlin 795) and nice on the .22WMR (CZ 452 Varmint). I don't regret it.

Hi Grimjaw...

When this topic came up about a month ago I wrote Winchester asking if they used different diameter bullets in the 22 WMR than they used in the 22 long rifles. They were a bit slow getting back to me but they finally assured me they use the same diameter bullets in both.

So - Ol' Joe's statement that the long rifles will be less accurate than the WMRs because the bore is "oversize" cannot possibly be correct.
If the WMRs are more accurate in your gun(s), it has to be for some other reason that may, or may not, affect all "convertible" revolvers.
Given how much the accuracy of .22 long rifle ammo varies between the Wallymart loss-leader stuff and premium ammo - my amateur guess is it's probably 5000% more likely to be an ammo issue. Since WMR cartridges are actually quite difficult to make, the process is heavily tuned and monitored and, I suspect, any WMR ammo is pretty darned good. And that's obviously not true of the long rifle fodder.

Just happens that the accuracy of 22 long rifles out of my Ruger "convertible" is quite good but I very rarely use bargain basement ammo in it.

An Thass all I know. :)

Why is 22 mag ammo more difficult to make?

Hi Outlaws...

As I understand it, it is due mostly to the length of the case - both the difficulty of making it while keeping proper and uniform thickness and also (I think) the case length impacts powder burn-rate in some fashion.

If I can remember where I read all that I'll post it here. :)

Just get a .22 mag rifle and tell the idiots at that ranges it's "just a .22". If they don't know a .22 mag from a .308, how'r they gonna tell a (for instance) 597 Remington from a 597 Remington magnum? Just walk in with it and smile, maybe buy a box of .22LR Remington Thunderbolt to make it look good. ROFLMAO!

I stand corrected. I have heard this so many times before I shot off my mouth without checking. Sorry!:o

The bullets are the same, it is the case that has different diameters due to the 22 LR bullet being "heeled" -the bullet base is smaller then bore diameter to allow it to fit down in the case which is the same as bore diameter- and the 22 mag taking a "straight sided" bullet and slightly larger diameter case with normal bullet seating.

i vote to get the magnum and find a new range.

Or, just tell them that it's a 22 rimfire ;)

The interesting part of this, is that I always hear about .22 Mag having a slightly wider diameter bullet than .22 LR.

So had I... guess I should actually measure things once in a while!
