Day1 22LR Accuracy Test: Ultimate Kidd 10/22 Build – CZ452 Varmint

| November 22, 2012 | 17 Comments

The 22Long Rifle is world renown and the most popular caliber by amount sold each year. What makes this caliber so popular is it’s versatility used for many different occasions, plinking, competition, practice, training and small game hunting. With the rise in cost of ammunition and the downward trend of the US economy the 22LR continues to grow in it’s popularity as it is the most economical as well. One can buy 500 rounds of 22LR ammunition at your local store for $19 dollars give or take a few bucks depending on your location. Compare this to $10.99 for 50 rounds of centerfire 9mm ammunition, $27.99 for 100 rounds of centerfire 223 ammunition and even $10.99 for 22 Magnum ammunition. You can quickly see why many are showing up to your local range with 22LR in hand. Of course there is always one caveat, in certain firearms 22LR though lots of fun can be inaccurate or unreliable. It use to be common to expect 5 to 10 dud’s within a box of 500 22LR ammunition. Manufacturer’s have improved tremendously on the reliability, but accuracy has always been about the firearm and the person pulling the trigger and if you are a serious competitor premium 22LR ammunition can become rather costly as well.

Unlike most whom grew up plinking and hunting small game with the Ruger 10/22 introduced in 1964 and the king of 22 Rifles sold, I grew up with a Marlin 60. Marlin is no slouch and I held my own with it against my buddies with 10/22’s but I always wondered what it would be like to own a Ruger 10/22. Many years later with the boom of something called the internet I was introduced to where I became fascinated with the Ultimate 10/22 forum, but only as a lurker reading post after post learning as much as I could from the experienced shooters. Having left 22 rimfire behind for almost 2 decades and fully immersing myself into everything centerfire I could not believe the wealth of knowledge which had congregated in one place. One thing that was most prevalent to me outside of the fun being had on and beautiful 22’s being displayed was that different firearms like different ammo which is the purpose of this review. Though centerfire suffers from this same fate it doesn’t seem to be as pronounced as it is in rimfire. So here I am 4 years later after first logging on to finally deciding to try my hand at building an Ultimate 10/22. Had it not been for DM a very close friend and my shooting compadre I still may be sitting on the sideline. DM started me on this build presenting me with a Tactical Innovations CH 22 receiver and bolt, a thank you does not even come close to showing my appreciation or gratitude for such a gift.

The unique thing about this combination is it wears a charging handle and charges like an AR15, something I had never seen before on a 10/22. This is also another benefit of building an Ultimate 10/22, personalization can be taken to the extreme or be as moderate as you like it to be. All other parts were ordered from Kidd Innovations Design except for the Tactical Solutions Stock, Tactical Solutions Rings and Mueller APV Scope which all came from Mizzou Mule Guns. The parts from Kidd were of great quality with tight fit though the website for me was a little difficult to manipulate but thanks heaven for telephones. I called up Kidd and the young lady on the other end of the phone was very polite and helpful. On the same day I decided to call up Dennis with Mizzou Mule Guns and get everything else I needed. This was a great interaction with a very knowledgeable fella who also knows customer service like no other. A few days later all of the parts arrived and Christmas has truly come early this year. Having unboxed everything and laying it out was a great feeling of joy that quickly turned to oh sh!t what have I got myself into. The wife didn’t help at all when she came into the room with bulging eyes and stating what was already on my mind “what have you gotten yourself into”? She then turned away shaking her head and mumbling under her breath something about the next time she see’s DM. For the sake of friendship I just hope the next time she runs into my comrade she is in civilian clothing and not her uniform. It would be devastating to read about a close friend having been shot with a taser for resisting arrest or guilt by association. The bright side is at least it was the taser.

With a few basic tools and having watched some of the video’s on Kidd’s website, 2 hours later there was a big smile on my face as I drooled over what I had just accomplished for the first time, building a 10/22 from scratch with custom parts. Instantly this put me on the path of trying to gather as much of a variety in 22LR ammunition as possible in hopes of discovering which would be the most accurate in this Kidd Ultimate 10/22 build. Again with the help of very close friends and a few trips to the local shops I felt I had gathered enough of a variety that I was bound to find something this build would like. While on my search for 22LR ammunition my intuition was really bothering me for having so much standard velocity ammunition for a 22 semi-auto. I was afraid some of it wouldn’t cycle the tight fitting bolt or fit the tight chamber of the Kidd barrel making my first range trip a disappointment and what a downer that would’ve been. This all proved to be inconsequential as all ammo performed reliably. Having amassed such a variety I got this crazy idea to also test this ammo in a few bolt action 22’s proving different ammunition shoots differently in each firearm. This could even occur on the same firearms built by the same manufacture. It was not uncommon for me to see two of the same rifles shoot the same brand of ammo differently, one being tack driver and the other patterning like a 12 gauge shotgun shooting bird shot. Could I also answer the question of – is it possible for a semi-auto to be as accurate as a bolt action? I was pretty confident in what the answer would be having watched some of the deadeye shots post their targets over at but figured it would be fun nonetheless, on this outing fun was the ultimate goal after all.

This testing would be conducted on two different days.
Both rifles and bores brushed cleaned with Frog Lube before heading to the range.
Before starting the shoot off I fired 10 rounds of Blazer Bulk through both bores, then one pass with a 22 bore snake was used.
For accuracy 5 round groupings were fired with the various brands of ammo without any scope adjustment, utilizing the basic sandbag rest front and rear. Between each 5 shot groups a 22 bore snake coated with frog lube was pulled through the bore and 1 Blazer bulk box 22lr ammo fired for fouling. By the way for those familiar with Frog Lube it smells so minty on the range doesn’t it? But I digress.

CZ 452 Varmint with 1LB trigger work

The CZ Varmint comes without the iron sights found on other models, but features a fine wood stock with nice checkering. The fittings for the swivels and the way this rifle is assembled make it as tight as many others costing far more. The shorter, but heavier, barrel is in balance with the rest of the gun, offering a completely neutral feel making it very easy to handle while hunting. The buttpad is soft rubber and isn?t tacky, so it absorbs what little shock there is from a 22LR and protects the wood from damage when placed in a rack. The bolt is heavy and smooth in operation and the single stage trigger was perfect, no take up, very light but still safe for critter dispatching.



















Weaver Classic Scope 3-9AO (Power was set to 8x for testing)







Of course the first up would be the Ultimate Kidd 10/22 Build, All ammo performed reliably except for RWS 50, for some reason it was a very tight fit into the chamber and the last round didn’t feed. A single drop of CLP on the 22 case while in the magazine and it fed that last round. There was pure joy and excitement when the average group size turned in to be 0.363 on it’s first visit to the range. Trying to keep the testing equal the Mueller AVP was set on 8x power as the Weaver Classic on the CZ 452 only went up to 9x but would be adjusted to 8x as well. This proved very difficult on such small targets at 50 yards. These targets actually were a mistake as I thought I had larger targets in my bag only to have discovered after I got to the range these were the only ones I had, and as my father would say use what ya got son and make the most of it.







Next up with the same batch of ammunition would be an out of the box CZ 452 Varmint with trigger work done to reduce the pull to 1LB. Average group sized was 0.358, though I did fire CCI Mini Mags. Long story short a fellow I ran into at the range would not stop bragging on CCI Mini Mag and he continued to persist that I try them. I didn’t want to insult the guy by not testing them considering he’d just handed me a box of them, even though I tried to give them back and pay him for them he refused.

By a close comparison the CZ 452 wins with a total of 5 groups to 4 groups of the Ultimate Kidd 10/22 Build. What I noticed on day 1 is the CZ shot the bulk ammo much better than the Ultimate Kidd 10/22. Could this be a sign of consistency or possibly the Kidd barrel needing to be broke in? The CZ 452 with this range visit has over 300 rounds through it now. Which gives it the win on total groups. Comparing group size the Ultimate Kidd 10/22 wins out with a smaller group with Lapua X-Act at 0.200. ?At 50 yards Lapua X-Act proved to be the top performer in both rifles. The worst performers were RWS 50 in the Ultimate at 0.576 while the Blazer Bulks performance in the CZ 452 wasn’t bad it was the worst of the bunch in that firearm at 0.397.


Cease Fire – Cease Fire on the Firing Line Day 1 Range day is complete.

While the day was a blast and I was leaving the range very happy with the outcome, I had already started to think about another session. Possibly a day 2 trying my hand at 100 yards and possibly including other 22 rifles and giving the Ultimate Kidd a chance at revenge. Stay tuned for day 2.

    Good stuff! Although not as scientific, I have had the same I experiences with my CZ452. Gave me some ideas on some more Ammo to try. Who fitted your custom stock on the 452?

  2. Bill,

    It’s not a custom stock actually came from CZ-USA this way with the thumbhole stock.

  3. Todd says:

    I generally shy from mall Rugers but this one works for me.
    Given the performance between the rifles was so close, I’d be interested to know how they age as the barrels break in.
    As far as the charging handle on the Ruger; it’s nicely streamlined, clever and well executed but isn’t it a bit hard to get to under the scope?
    What a great rifle to mildly suppress for bunny-bustin’.

  4. Todd,

    Needless to say it is going to be a joy breaking this setup in. The charging handle is a little of inconvenience but not really a hassle since I have very large hands and just reach over the top of the scope. Though I do believe this receiver setup would be perfect on a tactical build with a smaller red dot scope.

  5. J. Morris says:

    Thanks for the very interesting article comparing the two rifles; one factory, off the shelf, and the other custom. Rim fire shooters, I?m sure, would happy to have either in their collection and your article provides a basis of comparison of what they may expect. Thanks again for your work.

    One point I?d like to mention: Notice that the group averages for both rifles are almost identical, (Kidd.363) vs. (CZ.364). (I copied your chart to a spreadsheet, which leaves out the CCI group.) And then did the Standard Deviation for the two rifles: Kidd, 0.133 and the CZ, 0.032. And this is telling us that the CZ produced average groups with all ammunition tested, whereas, the Kidd was more discriminating. It liked certain brands and shot them well below the average, and other brands, not so much, shooting them well above average. Hence, the term average shooter. I think the accuracy potential would favor the Kidd rifle with a certain brand of ammunition.
    (?You pays your money, and you makes your choice.?)

    “And this is telling us that the CZ produced average groups with all ammunition tested, whereas, the Kidd was more discriminating. It liked certain brands and shot them well below the average, and other brands, not so much, shooting them well above average. ”

    I’ve found similar patterns of performance when comparing bolt and semi-autos in both .223 and .308 calibers. The semis might shoot a particular load better, but seem more persnickety about which ones they will shoot well.

    My Volquartsen barelled and triggered 10/22 can outperform my son’s 455, but for out of the box performance the CZs are amazing.

  7. LesC says:

    Just goes to show how poor the 10/22 is when to get the same performance as a $300 – $400 CZ you need to spend $1000 to $2000 over and above the initial purchase price of the 10/22.

    Personally, I would like to see a comparison of a bog standard 10/22 vs a bog standard CZ! That would be interesting. Or how about this tricked out 10/22 vs a tricked out CZ (Lilja barrel, Timney [or some such] trigger, good stock, etc). One doesn’t see much aftermarket gear for the CZs – -maybe because they don’t need mods to achieve their accuracy?

    Oh . . . and yes I am biased.

  8. LesC,

    What do you think about a review of a standard 10/22 against the custom 10/22, thus comparing like for like?

    I am getting quite a few emails about said comparison.

  9. DonS says:

    What’s the point of comparing a $2,000 dollar “Ruger” 10/22 that doesn’t use any Ruger parts vs. a box-stock real Ruger 10/22? Of course the faux Ruger is going to pound the real one. How about this: Since you mentioned the Marlin 60, how about a comparison of a stock Ruger 10/22 and a stock Marlin 60? That would be a fairer comparison.

  10. DonS

    I get your point but there is no way I could get away with paying 2K for 10/22 custom or not this build was not even close to that. This review was not about the firearms as much as it were about the ammunition.

    “Having left 22 rimfire behind for almost 2 decades and fully immersing myself into everything centerfire I could not believe the wealth of knowledge which had congregated in one place. One thing that was most prevalent to me outside of the fun being had on and beautiful 22?s being displayed was that different firearms like different ammo which is the purpose of this review.”

    But you have presented me with a good idea I think I may be able to borrow a Marlin 60 for this purpose.

    Thank you

  11. DonS says:

    Okay, I’ll concede the $2,000 was a bit of hyperbole ;), but the bottom line is your 10/22 clone is built from non-Ruger parts, designed and manufactured by people who got it right, which Ruger should have done in the first place, and it cost many hundreds more than a stock Ruger.

    I’d really like to see the results of the 10/22 vs M60 showdown. Heck, if you were anywhere near me, I’d loan you my Marlin 60. (I also have a 10/22).

  12. 😉

    I will get to work on it.

  13. LesC says:


    Any of the suggested rifle comparisons would be good (and a lot of work/fun doing the test).

    Something that I have always been wondering about is the accuracy of semi-autos versus bolt actions. Standard rifles only please.

    Line up 2 or 3 guns of similar quality and blast away. I’ll keep my eyes open for the report. : P

  14. Mark Timon says:

    I like the idea of taking a cheap 10/22 and doing a build with the remaining money to get to the same price as the stock CZ. Have somebody re-chamber the barrel and re-crown the muzzle, head space and redo the bolt, open the channel in the stock to free-float the barrel, have someone do a rework on the stock trigger etc and then compare the groups. Just to see if you can get similar groups for similar money.

  15. John Carter says:

    Thanks for posting this information. I have a Kidd on the way and really appreciate it. I was in the market for some very expensive .22 ammo only to find several cases where CCI SV works very well at a fraction of the cost.

  16. Jenny says:

    I purchased a ruger 10/22 for me and the wife to play on some steel plates knock downs. I got the 10/22 tactical , switched the barrel for a magnum research carbon fiber light. Wife complained that the stock full bull was to heavy. We have plenty of fun burning M 22 ammo up BUT when it comes down to competition Sunday at my range. I get out the winchester 52 c and the wife tears it up with her Cz 452 Varmint. The 52 is wicked scary!! The 452 has had the trigger worked down to 1 lb , removed the screw from the middle of the barrel. My smith cut the dove tail in the rear of the action and we placed the lug from the barrel into the action. Now my action has two screws holding it down. Last was taking a round brass ball with valve grinding compound and cleaning up the crown. With wolf match extra that I separate by rim thickness, shoots sub one inch groups at 100m with the wife pulling the trigger

  17. Jenny says:

    Bottom line is I never see anyone even trying to compete at our bullseye matches or Silhouette matches with a 10/22 even the super nice modified ones I see people playing with before the matches start. When they start, they get put away and out comes the bolt gun. Sorry guys if that ain’t what you wanted to hear but it’s the truth.
