.22LR in a .22WMR

minktrapper

Is it possible to fire a .22 LR in a .22 WMR barrel without anything going wrong.What happens when you fire a .22 LR in a .17 HMR barrel.
The Mink.

It wasn't me!

Opinions vary. Wouldn't be too comfortable with it myself.

You go and buy yourself a new rifle on the way to hospital, most likely. A .22 bullet isn't going to go through a .17 calibre barrel and all that pressure is going backwards, at you.

I presume that much but whatn else would happen I wonder.

In what respect? You'll send a lot of pressure through the rifle in a way that it wasn't designed to cope with. With gases blowing back you'll be lucky not to burn your face and hands.

Grossly inaccurate .22lr out or .22mag as it does not engage rifling properly

landkeeper

22lr head is the same diameter as a 22 magnumhead BUT the case is smaller diameter and much shorter therfore the bullet will be overtaken by some of the gases making it unstable and unpredictable
as afr as trying to fire a 22 out of a .17 i would be suprised if it would chamber but if it did and you pulled the trigger , all that energy would come out somewhere probably out through the bolt

robbie mars

i once upon a time fired a 17 hmr down the barrel of my 22 wmr (by accident) it fired the round but like that i wouldnt reccomend it

minktrapper

Not that much smaller .001 of an inch i believe.As for the .22 in a .17 Hmr must check the net for that.

How would it come out through the bolt.Blow a hole out the bottom of the bullet.

Would you put Diesel in a Petrol Engine?
Because some nut on the net said it was OK?

landkeeper

maybe but it'll be enough to split the case and still spit the bullet all over the shop
why do you need to check the net re .22 down a .17 tube thats just pure common sense or lack of if you try it :eek:

It is possible to fire a 22lr out of a 22wmr, but the cacing will most likely rupture leaving you with the projectile lodged in the barrel
No way is a 22lr going down a 17 bore...you might as well go all out and try to fire a .308 out of a .243 if you can get the bolt to lock in the first place...
you are asking for some serious injury and a new gun


were you the kind of kid to stick things in plug sockets by any chance:D

Muphys law. "what can go WRONG will go wrong"

Dont tempt faith brother. It's a good idea to read and understand the owners manuel you got with your rifle. There is also a warning on every box of ammo. Use the correct ammo for your rifle otherwise bad things will happen. That's about as simple as it gets.:rolleyes:

You can't put deisel in a petrol car, the nozzle is too big.
You can, as you say, do the opposite...

Back on topic. I agree with all the other posters. Don't try it.

When the super approves your application he does so presumably, on the basis that you are competent and responsible in the use and handling of firearms. And hopefully that you're a sensible fella.
So to consider firing a 5.5mm(.22LR) diameter bullet down a barrel designed for a 4.5mm???(.17) bullet makes a mockery of that presumption. Consider square pegs and round holes.
Don't do it and don't waste anymore time thinking bout it.

minktrapper

Someone is going to do it by accident sooner or later hopfully not me or any one of ye guys.Safe shooting everyone.

if you try this just to see what would happen ,then with a bit of luck you will blinded and you will have no need for a rifle any more.

.22 lr in .22 wmr

I neither know if this is true nor would I recomend it, but a guy told me he cut the rimmed end off spent wmr shells and was then able to push in a .22 lr round so the lr casing would not split in his wmr.

I think you would nearly need a press to push it in fully, and I would not want to be in the workshop when that is going on.

minktrapper

How would get it out after firing it.

To answer this.YES IT CAN BE DONE.
However you need a Chamber adaptor!!
This is basically a sleeve that sits into the 22 magnum chamber and accepts the .22LR round and takes up the excessive slack.

The other expedient method that the cowboy action shooters have been doing for years with the Ruger .22 magnum revolver is to simply save the 22 mag brass ,cut the base off them and insert a .22 lr rimfire round instead.This will work with some guns and not in others as you are talking very tight tolerances with expanded brass etc.No worries if the case ruptures as you are not going to reload them.

Maybe it is more pleasent in a handgun,as in a rifle.I would seriously recommnd eye protection,as there certainly WILL be hot gas and unburnt powder coming back at you,which I found out when I tried it.:pac:

Sofar I've only found one guy in Alaska of all places making these chamber adaptors.Dont know even if he is still in busisness,as he never answers emails,phone calls etc.Google chamber adaptors for his website

Do they have a practical use?Yes in certain circumstances,when a .22 magnum would be too much on a bunny,having one of these along is quite handy.Or for practising/zeroing they are useful,without burning up a load of .22 magnum.Are they fast?Absolutely not! They are a PITA to extract,reload and use.I've a single shot 22.mag and even then they are a nusiance to extract,so I dont know what a BA /Semi would be like,but more than likely down to a single shot.

I found that guy in Alaskas web site some time back, have it saved on my favourites list somewhere. Do you have any idea how the chamber pressures would react in the shotgun though?
