22lr reaming to 22wmr

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

Shiit, I'm always forgetting some of these rules :p You can't shorten Center fire below 18/18.5, depending on the action.
You can shorten a .22rf rifle barrel...down, as long as it's the 26" OAL? I thought It had to be 'Factory" still, for shorter 'anything' on barrel length.... no? -as per you quote to shorten to 16" ... ~

No shortening any barrels under 18" or the long gun goes prohib regardless of action or caliber.

Shortening a barrel for a semi auto centerfire under 18.5 but over 18 makes it go restricted

What you are thinking of is that you can _manufacture_ a semi auto rimfire with a shorter barrel with 26 oal (by telescoping folding etc). If the stock is not folding etc, then oal doesn't matter.

..lol No. That's exactly what I said. You CAN'T shorten centerfire. Under 18"..or 18.5", depending on the action.
Then I was asking about RimFire. As buddy above said you can shorten {.22} to 16". I was asking re:/about .22. What can / you shorten it {barrel} to? Buddy I quoted, made it like 16". I thought no, 18" is min.

18 _is_ the minimum if shortening. If you make a new barrel from a blank then you can potentially go shorter. Canadian laws are special.
 
I'm not sure if I'm miss reading here but just to clear it up,

you cannot shorten any barrel below 18" or its prohibited

if you shorten a non-restricted semi auto centerfire below 18.5" it will be restricted, unless you shorten it below 18" then its prohib

a non-restricted centerfire manual action can have any length barrel you want as long as the rifle above 26" over all length and you start with a blank and it will stay non restricted (not shorter then 105mm)

a non restricted rimfire, any action can have any length barrel as long as the over all length is more then 26" and you start with a blank (not shorter then 105mm)


there is a difference with cutting a barrel shorter and starting with a blank and making a barrel what length you want

Almost - minimal 26" oal only applies if the stock folds or telescopes. If it's fixed length then there is no minimal oal for manual action centrefires.

That's how these are NR

Also the "not shorter than 105 mm" is irrelevant - that's for handguns and what makes something a handgun is well defined in the legislation link I gave above (designed to be shot one-handed)

Sorry for taking this topic sideways but this is important or someone could get into legal trouble... so to bring this back....

Neither the CZ 512 (semi auto) nor CZ 457 (manual) can have their barrels _cut_ below 18" - they will be prohibited

They are rimfire so they do not have minimal barrel requirements otherwise.
Both have fixed stocks.

If someone were to make new barrels for either from a blank they would stay NR no matter how short - even down to 2"

But the OP is not looking to replace the barrel so cutting anything to 16" is not an option.

Well here's the update, Went from wanting a 512, to a 457 scout now to a 457 Royal on the Scout action, I traded one of my MTR stocks for this royal stock. Found a cheaper 16.5" heavy barrel. I opened up the channel on the stock to accept it. The reamer will be here in May. I'll get it reamed to 22wmr and see how she does. I'll shoot it a bit in 22lr for fun.

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.
