NEW 2010 CZ 452 SUPER EXCLUSIVE 22lr
« on: March 16, 2011, 10:17:12 PM »
I picked this 452 Ultra Lux up today from my local gun dealer, I was pretty excited to have found this new in the box. I have read a little about them and thought they were a thing of the past, But CZ must manufacture a few now and again. This gun has the Super Exclusive on the barrel and the box say's "Golden Features" on the label. Anyway, I cleaned all the factory grease and oil from it and went to the range. I am very happy with how it shoots, The trigger is absolutely sweet. Here's the first twelve shot. Considering a green barrel (Not counting factory shots) It's a keeper in my book.http://s1105.photobucket.com/albums/h343/Tinnoker/CZ%20452%20SUPER%20EXCLUSIVE/?albumview=slideshow

Hi

It is interesting to note that a .22 bullet has burned all of its powder in the first 18-19 inches of the barrel, which means that the rest of a .22 barrel should be doing little more than slowing down the bullet - but I so want one of these Super Exclusive models (not available over here - at least no one knows about them for ordering purposes)!

No sense in talking science to a CZ fanatic, ay?  ;D

Wish they made them with AA or AAA grade Walnut instead of the Beech though. Might have to buy one and get the stock made!   ;)

I think the long barrel's a sort of legal suppressor. ;D The report's a bit quieter than other CZs because as you said, the powder's burnt up by 18".

I think the oft quoted line about rimfires achieving their highest velocities in carbine length barrels (16 to 18 inches) is an urban legend.  Check out this test we ran at my club:


We conducted our barrel length vs velocity test on March 21, 2009 at the North Alabama Shooting Association range in Sheffield, Alabama.

We used five CZ 452 .22 rifles with different barrel lengths and fired six rounds each of six different cartridge types. The chart below reflects the average velocity of the six rounds followed by the standard deviation of the six rounds.

The rifles were:
CZ 452 Ultra Lux with a 28.6" barrel
CZ 452 Special with a 24.8" barrel
CZ 452 American with a 22.5" barrel
CZ 452 FS with a 20.7" barrel
CZ 452 Classic with a 16.5" barrel (Fuzzy the Limey's old CMP Sporter rifle)

The cartridges were:
CB Longs = CB
RWS Subsonic Hollow Points = SSHP
Wolf Match Target = Standard Velocity or SV
American Eagle Solids = Lead High Velocity or LHV
CCI Mini Mag Solids = Plated High Velocity or PHV
CCI Stingers = Hyper Velocity or HypVel

-------CB------SSHP----SV-----LHV------PHV----HypVel

28.6 652/53 968/16 1037/13 1206/16 1188/24 1660/50
24.8 676/34 997/20 1062/13 1219/22 1217/40 1660/47
22.5 653/65 998/08 1069/10 1229/22 1213/24 1708/31
20.7 701/44 957/39 1062/05 1224/14 1190/11 1661/26
16.5 685/22 949/27 1057/14 1205/17 1208/22 1666/39

Hi Sheffieldshooter

I think you are right, the optimum length (from your figures) appears to be 22.5 inches of barrel length - not the shorter lengths that some companies propose (eg Kimber).

Your figures do show though that there is no advantage in anything longer than 22.5 inches in the .22 LR class (unlike centrefire rifles that may be still burning powder out of a 26 inch barrel).

Good science! Well done.  :)

I will agree.  I purchased a 452 and a 452 super exclusive in a two day time span.  First time out, both guns, 5 bullseye shots.  My favorite  guns.  Period.  They are very difficult to find.  These make my 4th and 5th CZ.  I really think they are the best guns out there.

There certainly may be an optimal barrel length when considering velocity. The problem is accuracy and velocity are distinct and the choice of barrel length is really a function of intended use.The extra length of the Lux offers a real advantage for iron sight shooters. The extended sight distance is a big plus. The excellent tangent sights offered on the 452 Lux matched with the hogback style stock are a great combo for accuracy. If I am looking for a small game rig the shorter barrel models will be quicker handling and offer all the accuracy I need for a rabbit shot when in the field.

I call BS on all the velocity things concerning why you would build a CZ- UL.  That long barrel increases the SIGHT RADIUS. thus increasing accuracy of the shooter.  Simple as that. :d
