22lr reaming to 22wmr

Interesting. I wonder why they say you can't use a Super Wrangler cylinder in an old wrangler then... That would be a real nice addition to my Wrangler if its only lawyer talk and not actually incompatible...
About a year ago, I took a chance, buddy had listed here 'Complete/minus frame' Ruger Single Six .22lr'. I think it's an older one..but low & behold, the Cylinder fits/works Perfectly in my newer Ruger Wrangler. {last Restricted b4 the ban!!} Then I bought some other various parts, I think off the same guy later on, including a Ruger .22 Magnum cylinder, hoping to get lucky, but No Go, didn't fit.

There is a couple threads on USA forums I've found, of people converting the newer / .22 'only' Wrangler to Magnum, by reaming just the cylinder.
I'll find them again & link them if you like. Basically, what I was told is Ruger stopped making .22 only' Single Sixes. All their barrels are the .224 now, so, there was no need to ramp up costs on the cheaper Wrangler, so they used the same tooling./set up.{.224}

I only know the Wranglers that are more recent..they came out maybe 5 years back or so? There is older ones too? Still, pretty weird/lucky, that one old cylinder actually fits/works perfectly.

No, there is a brand new one, Super Wrangler, in 22wmr/22lr. But they say this about using the cylinder in the old Wrangler:

If the handgun ban ever lifts I'll be looking to get one of these, adjustable sights is a big upgrade to me.
 
22 mag and 22 lr may have the same pressures but that's with the correct bore. You have to consider that the pressure will increase with the smaller bore on the 22lr barrel . Gunsmith in Sask. does lots of conversions on Cooeys and says they work well.
 
I have your solution...

Forget the CZ 512 or re-barrelling a 22lr.

I was in the market for a 512 also, until I saw a Volquartsen SF-1 in 22WMR for sale. I ####ing love it. Super accurate and gorgeous rifle.

Yes it will cost you more but the accuracy, reliability and cool factor is worth it IMO. It also accepts 15 round BX Magnum magazines. Which are available and legal in Canada.

They have Semi-Auto and straight-pull bolt versions in many configurations. If you can find one used you can save some cash. I don't regret my purchase.

A straightforward job, but no smith is going to go out of pocket on the reamer for what may well be the only job they use it on in their career. If you supply or pay for the reamer, you shouldn't have a problem finding someone willing to do the job. There's such a wide variance in bore diameter specs, I don't see any issue using a former .22 LR barrel for WMR. For .22LR, SAAMI spec is 0.217" while CIP is 0.2118", a difference of 0.0052". The headspace on WMR is larger, so the tenon length will also need to be shaved back to accommodate the change. 457 bolts accommodate all the different calibers offered in the line without modification.
 
A good thread! I am considering similar - I have an elder Savage "Camper Special" - so 20" barrels - 22 Long Rifle on top and 20 gauge underneath. Is no "bolt face" to worry about - hinge action - I will just have to verify that the rimfire firing pin will strike the 22 Magnum appropriately - I believe Savage did make some versions of the Model 24 with 22 Magnum barrels, but I do not know if they were different diameter or different twist rate, or if the receivers were done differently. I will probably run a slug through that .22 bore, before doing anything, though - I will want to "know".
 
So, thinking about it - I presume a 22 Magnum chambering reamer has a pilot. I assume that is meant to ride on the tops of the riflings - does anyone know if that dimension is the same between 22 Long Rifle and 22 Magnum?
It's different for every barrel and each barrel maker has their own target spec that they will be + or - tolerance on. Live pilot reamers use a bushing that the smith picks out of their bushing set to best fit the individual barrel they are working on.

Agreed, I'm was trying to find a Smith that may have one on hand before I make a purchase. I may just order the one on Amazon, it's a generic photo, so it's a bit of a gamble of what it will actually look like. lots of options state side, not so much up here.
 
you have yours answers looks like the experts think it's a easy change up so go buy the gun for x amount of$'s get the work done for x amount of $'s then post photos of the finished product with video on how it functions and total cost of finished product
looking forward to the results

Rifle was ordered today, A fluke, Tillisonberg did some inventory and found a single cz457 Scout rifle and listed it this morning, just happened to be browsing there. snapped it up right away, Traded a 457 MTR stock for a 457 Royal stock today as well. so I should have a 16.5" Iron sighted 457 royal which I've never seen before. and have it chambered in 22wmr. as a bonus I'll have a youth 457 stock for when my little ones are a bit bigger, also have another scout barrel right now on a 455 in a LUX stock. so if I wanted to convert fully back to a 457 scout I would need an additional 457 action. as it stands now the tally is $650 for the rifle
$65 for the reamer
 
EDIT, New Route, Post #7

Alright guys, hear me out. Been in the market for a cz512 in 22wmr. I know they have been discontinued. And the unobtanium +1k used price tags on 22wmr throws me off a bit.

My local shop has a 512in 22lr on the used rack for a good price. my question is.

do you think I could have the barrel reamed to 22 magnum?

The action length is the same on both rifles I'm pretty sure, you can see the spacer on the 22lr that can be taken out to accept larger mags, just like on their bolt action rifles.

my concerns would be different twist rates and also different action spring of course, springs could be an easy fix it was an issue.

Am I out to lunch for considering doing this? thoughts and input are greatly appreciated.
It used to be 1thou.diff on bore size i don't know if that still applies
 
Go here - SAAMI rimfire specs - https://saami.org/wp-content/uploads/2022/08/ANSI-SAAMI-Z299.1-Rimfire-2018-Approved-2018-06-13.pdf

It appears that maximum size 22 Long Rifle BULLET is 0.2255" diameter and minimum 22 Long Rifle bullet would be minus 0.0040" of that - so 0.2215" and that small one would still meet SAAMI spec for 22 Long Rifle - bore is given as 0.217" and groove as 0.222"- page 15

For 22 magnum, it appears the BULLET is smaller diameter than 22 Long Rifle - 22 Magnum given as maximum 0.2245" and minimum minus 0.0040 from that, so 0.2205 would still meet SAAMI spec. Bore for 22 Magnum is larger than 22 Long Rifle - 0.219" and the groove size is also larger than .22 Long Rifle - 0.224" - page 18

So, it appears that SAAMI specs the bullet for 22 Magnum to be about one thou smaller than for 22 Long Rifle, yet the bore and groove diameter are two thou bigger than for 22 Long Rifle.

Double checked the reamers I have and only have the 22lr, no wmr. Have a very diverse bushing kit though...

I would suggest buying the reamer from PTG direct, they will ship to Canada. I think I know what reamer you found on amazon (hammerbutton?) and they are crap - they are not set up for a bushing pilot, not set up for a holder and may end up being 22lr. Might be ok if you are making an illegal zip gun, but don't subject a nice rifle to that please...

I agree with what someone said - if you provide the reamer, you'll have no trouble finding someone to do it locally. I know I would have if I were.

Good luck!
 
I’d MUCH sooner pay the little extra to buy the cz in 22 magnum. Or just a 457 22 magnum barrel. Instead of messing with this stuff and bore diameters.. who cares about 16” barrel vs 20”. I’d take the cz Barrel that is chambered 22 magnum from factory instead of one that’s got the wrong bore diameter.

and that's your preference.
 
You could also buy a factory cz 22 magnum barrel and have it shortened to 16” length. That would be the safest bet I think, just in case the slight bore diameter difference will end up mattering accuracy wise. Less chance of things going wrong anyway but if one likes to tinker alot and experiment that’s cool

thanks for the info, requested a cancel from Amazon. I'll look into PTG, thank you very much!
