I have recently been offered a vierling in 16x16x8x57JRx22LR The 22LR is in the center of the barrel cluster, not in the rib. Can the 22LR just be lengthened to 22Mag or is there some difference in the bullet weight or twist that would prohibit that?
Thanks,

I think this would be a VERY bad idea, as there's a difference in bullet diameter between the two, with the mag. being a bit larger in diameter. Also, the mag. case is quite a bit larger in diameter too, so where would that rim fire fireing pin hit it? And what about the sights??? Where would this bigger, faster bullet hit???

If you want a 22 mag. in this gun, get a Krieghoff 22 Win. Mag. insert bbl for one of the shot bbls!

Can you post some picts of this gun, i for one would love to see it!!

dherr, The bore is the same but the 22mag case is larger in diameter as well as longer. You can buy or rent a finish reamer and do the job yourself if your handy with tools. I have a cylinder reamer, but they are for revolvers and won't work for your application. Regards, Byron

The bore is not the same...

22 Win, mags measure .224" and "most" 22lr's i've measured are .222"... Then there's the fact that the mag. bullet is jacketed (read goes through the bore harder) and the lr bullets are pure lead, sometimes "coated" but never jacketed...

one thing to remember is that 22 lr uses a heeled bullet and only the part outside is full caliber and the 22 mag is a true224. yes you could do a conversion. It would be expensive and arduous. What is wrong with the 22lr? I agree it would be easier to just insert one of the shot barrels. I mean the 8x57 would cover anything above what the 22 wouldn't. Not to mention the shot barrels. I am not sure I want to see a pic= I'm already green with envy!

DM is right of course. There is a 2thousand difference in bore specs. How accurate that will hold true in individual guns would need to be measured. I don't believe every gun will be exactly the same.
I've had several S&W revolvers re-chambered from 22lr to 22mag and they worked fine with no pressure signs. were accurate and the fireing pin consistently set each round off.
I've had no personal experience with rifles. Not trying to argue but even with a 2thousands difference would that be dangerous?

I have contemplated and researched a similar pet project of my own and am looking for a H&R/NEF Versa Pak .22 LR barrel to convert to a .22 Mag. As soon as I can locate and purchase the barrel I need I am going to do it....<><....:)

I would not do this, you could mess up the sight regulation, not to mention a very fine rifle. It seems a risky proposition on an expensive gun like this. An NEF Handi-Rifle isn't much to lose.

22 Mag Ammo is ridiculously expensive to boot.

22 LR shoots fine out to 100 yards (obviously with some bullet drop) so I don't see the need.

What is your purpose for wanting the 22 Mag?

Dave,

A good friend of mine recently purchased a Thompson Contender barrel that was converted from 22lr to 22 mag by reaming the chamber. It shoots great, very accurate and no ignition problems.

The "original" question was about converting a "vierling", not a TC, not a Ruger, not a S&W and not about any other "modern" American made firearm...

I hope the origional poster understands that a "vierling" is not over built like any, and all of these other guns are, and is designed in so many different ways compared to a "normal" firearm that it's ridiculous to even compare them...

Hi guys, I ended up with 2 H&R .22 LR "Versa Pak" barrels and I had one reamed out to .22 Mag with a rifle reamer. It took the gunsmith about 15-20 minutes from the time I entered the shop and we talked until it was done. My .22 LR, now .22 WMR barrel, shoots GREAT!!! It is very accurate at 50 yards with iron sights, shoots and ejects fine and was a complete and wonderful successful transformation of the barrel. The .001" is nothing to worry about and the firing pin strike from .22 LR to .22 WMR is not a problem either. The only problem I have now is I want to have the same thing done to my other .22 LR "Versa Pak" barrel, but since H&R has stopped production of them I would like to keep one as manufactured. I am continuing to search for one more .22 LR "Versa Pak" barrel to have reamed to .22 MWR. For any that are thinking of doing this to another gun I say do it and don't look back. Those who oppose it are those who have not done it and know not of what they speak, they are only repeating fears they have heard other unknowing persons voice, try it you will be happy!!!....<><....:)

I will say to alter a possibly collectible drilling would be akin to a sacrilege, so think long and hard before you do anything to it. I do nor believe it will harm the gun, but it will not be "original" after the reaming to .22 WMR...

P.S. anyone out there have a .22 LR "Versa Pak" barrel they would sell me?....<><.... ;D

Could you kindly please tell us how many "vierlings" you have ever fired or have had apart in your life?? How about even "handled"?? Do you even know the difference between a "drilling" and a "vierling"??

Some how i don't think someone who is running around buying H&R's knows too much about drillings and vierlings... Certainly not as much as those of us that OWN them and have "worked" on them...

BTW, it's called "re-chambered" not "reamed out"... And it's a "chamber" reamer, not a "rifle" reamer. If you want to make us sound stupid, the least you could do is make yourself sound smart.

MSP Ret and DrillingMan

I am confused.

MSP Ret do you have the inserts installed in a Drilling or Vierling?

DrillingMan have you used H&R Verspac in a Drilling or Vierling?

Doug,

The versa pack is NOT an adapter... It's nothing more than a H&R single shot with a couple bbls... The bbls are heavy built and can stand some rechambering, unlike the bbls in a veirling or drilling that are made thin to save as much weight as possible...

"I will say to alter a possibly collectible drilling would be akin to a sacrilege, so think long and hard before you do anything to it. I do not believe it will harm the gun, but it will not be "original" after the reaming to .22 WMR..."

I am sorry if I offended you Drillingman, I have in the past read some of your posts and in the past have enjoyed them. As to your questions about my experience with Drilling's or Vierling's I will say it is next to nonexistent, nor did I ever say I was knowledgeable about them, especially not when compared to someone with your boundless knowledge, empathy, and compassion. I have however handled several Drillings and have long felt I would like to someday have one but do not think I ever will. I was speaking of my experience with converting an H&R .22 LR Versa Pak barrel to a .22 Mag. I bow to your extensive knowledge of all things pertaining to guns. I was referring to something I had done to one of my guns by an excellent and experienced gunsmith. A pistol "chamber" reamer is not the proper tool for the job, a rifle reamer is required. I did not have the barrel rechambered but the existing chamber reamed out. If you want to argue semantics you can call it a rechamber, it's OK with me. I mentioned the conversion from .22 LR to .22 Mag because that was being discussed, and also for some reason some unknowing persons continue to believe and repeat the unfounded and improper belief that a .22 LR rifle cannot be easily, simply, and safely converted to a .22 WMR. Those people speak foolishly about the difference of .001 as if that in itself makes to conversion impossible. Granted, not all conversions may be prudent, but that in itself is not reason enough to prevent the work. I honestly hope I did not offend your sensibilities, I think these 3 barreled guns you seem to hold in such high esteem are really great. I call them 3 barreled guns in deference to you, because I do not want to have to read your attack on my less than knowledgeable statements again. I was merely offering information on something I had done to one of my guns and how it worked out. I am sorry and apologize for offending you. All the best to you, your endless knowledge of all things concerning all guns, and your expensive guns as well....<><....::)

I did not want to stoop to your level but after all, we are just trying to enjoy our own hobby, to learn from one another, and to exchange thoughts and ideas here aren't we? As Rodney King once said, "Can't we all just get along?", evidently not, if something is said that is not agreed with... :-\

P.S. - be very very careful dougk, he may turn on you if ho does not like or agree with what you say, or if have ever enjoyed an inexpensive gun....

Interesting read pertaining to the .001" difference:

"We make far too much of .001" in bullet diameter, so long as it chambers easily .001" over groove diameter is nothing. P.O.Ackley once did a pressure test with a .270 barrel. He first fired a series of shots with a certain powder charge behind a 150 grain .277" bullet and recorder pressures. He then opened the neck and throat and loaded a 150 grain .284' bullet and fired it down the .270 bore, same powder charge produced the same pressure. He then went on to .308, .312, .323, and finally .358 all fired down the .270 bore and with the largest sizes pressures became erratic but all averaged about the same as had the .277" bullet. Another gunsmith who's name I don't recall did a similar test using an old SMLE action and also came to the same conclusion, so long as the neck and throat are not too tight, even grossly oversize bullets do no harm."

I will go back to my poor mans rifle section now Drillingman, you are welcomed over there to voice your opinion anytime, and you will not be thought of badly for it, even though as you said, " I don't think someone who is running around buying H&R's knows too much about drillings and vierlings". We may be second class to you but that's better than no class. Come on over any time, all is forgiven....<><.... :-*

(And by the way, my Handi can outshoot your Vierling!!)

I believe what we have here is "A failure to communicate" You are both correct given your points of view/reference.

If I were to purchase a single shot rifle it would be a H&R or Handi as they are fine guns.

First of all, i'm not offended, not even by your attempt to make fun of me... But lets clear some things up...

I'm NOT always right, but if you say i'm wrong, bring some proof with you... Don't just state (and i quote)
Those who oppose it are those who have not done it and know not of what they speak, they are only repeating fears they have heard other unknowing persons voice
and expect me to roll over because you say so...

The thread was about RECHAMBERING a vierling... Not anything else... There's a world of difference between a gun/bbl that's made "as light as possible" vs something made many years later and overbuilt. I addressed this eariler in the thread...

I've measured many 22lr bullets and also 22 wmr bullets... The difference is accepted to be .222" vs .224" and you have to add the wmr bullet is "jacketed" so it doesn't slip down the bore as easily as a pure or coated lr lead bullet... (keep in mind the thread is about vierlings)

It is called re-chambering as you are "re" chambering a bbl that's already chambered... I personally have done the conversion your refering too myself...

I wouldn't have thought twice about this had you started a new thread about re-chambering a modern gun... Stateing what you did where you did may get someone with an old very lightly made gun in trouble....

Lastly, if you want to talk about Parker Ackley, we can do that too... I visited him several times in his shop, and spend many hours visiting with him about all kinds of things...

you are correct AGAIN Drillingman, but we all knew you would be. I agree some .22 WMR bullets are jacketed, I also know that some are not, but you knew that of course, not that it has anything to do with it. That is of course unless P.O. Ackley was wrong. But then again, you knew P.O. Ackely, and I'm no P.O. Ackley, that's for sure. I have read his writings to learn, not to criticize. Why I am sure you taught him all he knew. Don't be upset, I admire someone who knows everything and is willing ti display that belief.
dougk is correct, I also believe this difference is merely a "failure to communicate". I am sure I have much to learn from Drillingman, for as I have stated I know little about these fine expensive guns he knows so much about. Sadley that may not happen. Have you ever had a favorite teacher, one who you enjoyed and actually learned from? Do you recall any teachers you did not favor or enjoy in the classroom? They may have had the knowledge, but.......

....<><... :(
