CZ Canadian 17HMR

Got mine in 22wmr.. and yeah its a keeper ! Its great !

Very different from cheaper guns.. Its my first CZ and now Im looking into the 452 LOL!

Seriously the fit and finish is just on par with my FN Winchester M70.. So its pretty :)

No. No. Just one for me, one for my buddy. Calm down Looky. :p

But I'll let you in on a sure bet - if I like the .17 Canadian, I will be ordering a .22 and a .22WMR. Only makes sense to keep things nice and balanced. 3 Americans, 3 Canadians. Will also probably need a 455 FS to keep the 452 FS company.

:dancingbanana::dancingbanana: It's here!

Looks just like the one in the pic above. No chance to scope it or fire it yet. Typical CZ gritty action, but some loving care, working the bolt, has already smoothed it out a bit. Everything seems to fit nice. I'll clean the barrel of any dead flies, etc., mount a scope and try to give it a few rounds before I make any wild and wooly comments about the accuracy. My 455 American .17 is laser accurate, even with me shooting it. There's proof right there that guns do have a mind of there own. The way I wobble around, the gun has to be helping out! :p
 
My buddy says his 455 Canadian is 3/8". I bought a set of Burris rings - too big! I only tried the set this morning, but they are definitely not going to tighten. The young guy at Wholesale said they could fit both by flipping the moveable clamp. No workee. The clamp is not made to be reversed. It looks like my 455 Canadian is 3/8".

On my way to Dauphin to get work done on the wife's new truck, I stopped and smoked about 20 gophers in a field I shot in 2012. :). That sort of eased the pain of not being able to scope my fancy Canadian. :(
 
I put Leupold 11mm rings on mine and they fit perfectly. Pretty sure the 3/8th inch rings are actually bigger than the 11mm rings. The 11mm measures from the top of the dove tail where as the 3/8th measures from the bottom of the groves of the dovetail and actually measures 13mm across on the top.
 
3/8" = .3750

11mm = .433071

Some 11mm rings may clamp down far enough to tighten on 3/8" dovetail. The Burris ones I bought sure don't. I bought some el cheapo Weaver rings today and mounted the scope. The rings I used might fit an 11mm...maybe.

I'll see if I can do a rough sight-in tomorrow. Deaner and I are going out to do our civic duty for a farmer who called me yesterday about a hotspot of gophers. I'll have to miss a few intentionally so Deaner doesn't sulk too much...:p

This is from the DIP site, Europe measures dovetail by the top dimension, US measures the bottom. If you go to the DIP site and look at the rail size chart it has all models of CZ.

If you are NOT sure about the dovetail size of your CZ, measure the widest part(top):

Approximately:

.500 = 3/8

.430 = 11mm

I also posted the dovetail size chart for every cz rimfire on page 3
 
Thanks for the info/help on the rings etc.

Initially I put Weaver brand 3/8" mediums (bought the rings based on retailer's description of gun when I ordered it) on my Canadian Edition. They fit but the gap around dovetail had gaps and bolt just barely cleared the scope. If I was to pull bolt back quickly it would rub.

Installed a set of Talley 11mm highs (after CGN folks confirming they used same rings) and they fit the dovetail perfectly. Scope is a bit higher than I am used to but bolt clears scope cleanly.
 
I have 5 cz 455's and they are all 11mm and just measured the new Canadian model and they are also 11mm not 3/8".
Some ring clamps are designed to flip the clamp and some are not. Leopold rimfire rings can be flipped and Warne also.I have these rings and the info on flipping comes with the rings.
All the info on the Canadian maple leaf 17hmr and 22lr are typo's and nothing else.Hometown's posts are correct.

Well, I give up. Whether the Canadian 455's are 3/8 or 11mm matters not to me. I put an el cheapo set of Weaver rings on, had my buddy Davey torque the action screws a couple of times until we got it grouping good, and set off to shoot gophers! It is laser accurate like its American cousin. I was interested in the difference that the proper torque made to grouping. Davey put two shots within 3/4" of each other at 100 yds. I generally spread my shots around a bit more...:p

Being twice as fast as most .22, it is a real blast to smoke gophers way out, while holding the crosshairs right on the target, and hear that "poch" almost instantly. :cool:

I had him do the torque thing on the American as well. Made quite a difference! Next will be my American .22 magnum. Couldn't hit the broad side of a barn with it today. I have a 455 .22 as well, but no scope as yet.

Just need to clarify something - BURRIS Rimfire/Airgun Rings #420071 will not tighten on a 455 Canadian. Does that mean that, although 11mm is actually bigger than 3/8", the actual, physical size of the dovetail on an 11mm 455 is smaller? It seems to be a difference of European and North American methods of measuring the dovetail, as someone above has mentioned.
 
I went through this rigger-ah-mole with my CZ 22LR American.
Nothing seemed to fit right.
I bought the same rifle in 17HMR and the Burris 3/8 rings fit better than the
custom CZ rings.
Go figure.
Just need to find my CZ 22 and see if these same rings will fit this receiver.

Drove me bawnkers, I'll tell yah................:runaway:

The 455 are all the same dovetail regardless of the model.They are 11mm. That measures .430" od measurement at the top of the groove. The rings you refer to are called a 22 ring and the clamps must be reversed to fit a 11 mm dovetail. Read the instructions.

http://www.burrisoptics.com/mounting-systems/rings/rimfire-and-airgun-rings note at bottom reverse for 11 mm. The spec tab has all the info also these rings only made for 1" tube not 30mm

I don.t have any 3/8" cz to measure but believe the outside top measure about .503" The clamps out of the box are set for the 3/8" that are wider. Flip the side clamp 180 degrees and they now are set for 11mm that measure smaller. Flip yours over and install. That's all very simple.

No need to get huffy. The BURRIS RINGS #420071 that I have do not have reversible clamps. These particular clamps are NOT made to reverse. The holes don't allow it. I did read the instructions. It isn't all very simple.

Last post on this subject. The dealer we bought the rifles from told us they took 3/8" rings. He has installed several.
