You're the man Kenny! I am so happy and proud of your work! Being an Iscar rep I will gladly say you are on top of your game and spared no expense on quality machinery! Unlike many machinist in the world, you understand rigidity and think outside the box on how to machine accurate barrels and actions. Thanks for sharing and keep up the amazing work!

Keep up the good work - one sees very little of that dedication and expertise nowadays.

[@donschutte1418]

I am from Canada and back in the 90s I was buying CZ actions for 69.00 from Lever arms they all had barrels attached but they were only about 12 or 14 in long cut off with an abrasive saw or something. We used to take and recrown these barrel stubs and screw them into a stock and without exception everyone would out shoot most anything you compared them to. Out of at least 30 or 40 actions that I purchased not one was a dud they were all very good quality and built fine rifles on them putting new barrels of course

[@jeffreypelletier7247]

[@Tbowie13]

This is awesome! I gotta look into your work more. I bought a Christensen Ranger after being happy with a Christensen MPR 6.5cm purchase. The Ranger was so bad I sent it back 3 times and they eventually bought it back. I then got a cz457 chassis model and liked it so much, I got another 457 Match Varmit Precision with the flat bottom Manners stock for an arca lock rail. I suppressed it with a "DA mask", Atlas bipod, Audere rings, Vortex PST scope. It's a tack driver. Prob the most accurate rifle I have, high dollar centerfires included. It sure would be awesome to get a little more performance out of it!

[@rcg3496]

Loved the subject matter, clear presentations, and detailed explanations… Thank you sir🙏🏾

[@tonyharper8056]

Great stuff Kenny. The reason for chambering after cutting and threading the tenon is because changing the outside of the barrel results in changes to the inside of the barrel. If you make all your outside cuts first, you don't change your chamber dimensions later. Try it both ways and cast both chambers and measure you will see a difference. Slight maybe but it will be there. The cast will show the differences better than simply measuring.

[@EagleEyeShooting]

Ive tried both ways and the only way ID measurements get changed is overheating the tennon area. It's better to chamber before if you know how to controll your cuts

[@sjohnson1776]

Thank you for bringing us into the shop. Much appreciated!

[@Womfat]

So much great info in the video! Your attention to detail as usual, now paired with the new machinery is really making some unmatched rifles. The proof is in the results. Dorys new threaded CZ is an absolute beast and outshoots my vudoos. My next rifle will most definitely have one of your in house barrels.

Great video, Kenny...and I thought you were taking the 4th off!

I would not use the 1/8" wide grooving tool to finish the tenon shoulder. These will always deflect resulting in a tapered (conical) face. A standard vnmg or dcmt od holder will give better results and allow you to program .0001-.0002" concave taper if you wanted.

[@user-dm7co8qy1t]

Awesome info, thank you.

[@austinkroe]

Excellent video. Can’t wait till I can save the money to order one of these to go along with my thermal fit that you did. I’d say the biggest downfall for me on the 457 is the lack of triggers that are on the market. There isn’t a two stage out there and the selection is tiny compared to the 700 footprint actions. While the triggers that are available are nice they just aren’t what I would like and I think the other actions have that advantage over the 457… just not enough of an advantage to make me want to switch platforms. I think the 457 community is blessed to have you. Sadly it seems we may have lost one of the other big contributors to the 457 being able to overtake Vudoos and Rim-Xs in competition; Bill Scaramuzzo. His triggers were the absolute best for the 457. Sadly it seems he’s out of the picture. I have one of his two stage triggers and I wish I would have bought four of the dang things when all I thought I needed was one. I wish someone would start making them to his design and specs cause I’d buy a bunch of them. It’s so much better than the Jard or Timney. I wouldn’t trade that trigger for a complete build 457 if you put a gun to my head. Someone needs to put out a good two stage for the 457!!! Do you have thoughts on two other possible shortcomings of the CZ; that being the scope mounting interface not being as secure as some other actions and the fact that the bolt lockup is asymmetrical (ie only one lug)? Obviously the 457 leaves some things to be desired but it’s still great. Looking forward to seeing your benchrest build video to see what fine little details you squeeze to make a gun even more accurate than the CZ you put together in this video.

[@genecoffman3577]

Fantastic video. If I was a youngster my check would be in the mail.

Hey Kenny! Great video. Would it be possibe to thread a Tikka T1X action? I’ve heard the barrel change is kind of a pain because the action has an ovoid shape and maybe threading it eliminates the problem and a blank can be customized.

Hi Kenny - Love your work, a perfectionist! My brother was a good machinist so I have an appreciation for this work. I am leaning towards getting a CZ 457 and from your shop. I do have a question about your newer threaded barrel process. I hope it wasn't already answered. Are you 'facing' the reciever's barrel insertion end to match perfectly with the barrel shoulder? I know other rifles seem to benefit from this practice. It is more time consuming as you may need to measure how much is faced off and add it to the barrel measurement. Best Regards -Bob

[@EagleEyeShooting]

@robertgartner6072 hey Robert, if your referring to the receiver face. Yes, I square up the receiver face where the shoulder of the barrel meets the receiver. I usually take out anywhere from 1 to 4 thou. This video, I removed 3 tho. At the end of this video I actually have a diagram of this receiver that I drew and showed how a prefit would sit if this action wasn't trued up

[@cz503]

Thanks for your time. I am not Mashinist but enjoy your explanations. Can't wait for BR video. Don"t really understand why you don't apply those " BR secrets" to PRS rifles (understanding difference on accuracy expectations by both discipline) . By end of the day everybody is looking for most accurate rifle isn't it ? Shooting good with few different ammo is head space lucky number right? But up to some point where ammo capabilities dictate results. On 50 yards my rifle shoot 5 different brands with same results. On 100 yards things start divide and 200+ one brand stands out. Really wanna see this rifle and shooting ammo from 5$ up to 30 $ per box on 150 -200 yards . My custom barrel is glued to the 455 action ( with proper squaring and hand space ext ) and is something between yours heat and tread fitted rifles. What do you this about gluing fit like mine? Thanks

[@EagleEyeShooting]

As I briefly explained in the video (I know it's long) I can't use tight chambers as I would in a small bore BR build. You will loose ability to extract reliably. The barrels are also built different, causing a cold bore shift. Something a PRS displines cannot afford to have as you will drop points. Glued CZ457 barrels are not a solid inference fit. Just like any epoxy based substance, it will flex. Theirs loctite 680 or equivalent that is a better option but still not as good as thermal fitting or just having it threaded. It's just a nightmare to remove. Perfect example why I don't take in people's CZ457 actions. Folks just FUBAR the system and expect the same results

[@cz503]

@@EagleEyeShooting My rifle is with loctite and it takes very little preheat and small hydraulic hand press for barrel to come out. Interesting point on different barrels build and cold bore shift. What cause cold bore first and/or what's difference on those two type of barrels and most important how one barrel build dictate cold bore shift to be present or not? Would be nice to learn more about this . We just went into a rabbit hole and I know how valuable your time is.

[@EagleEyeShooting]

@cz503 if heat loosens the loctite, I guarantee its not the best loctite to use. A retaining compound is what is recommended to fill voids. I would look into Loctite 680 as its designed for cylindrical slip fitted applications like how the CZ457 barrel is designed. Loctite 648 for high heat applications like an AR15 barrel. It's a PITA to thoroughly clean out of the action tennon area once applied however

Hello I would like to write some corrections here. 1) Actions are not casted but machined from solid crome moly steel rods. Steel casting is only used for steel pistol frames in CZ 2) action is not parkerized but nitrided like most of steel parts made in CZ. There are some exceptions that are blued but many. 3) barrels are not button rifled but cold hammer forged. CZ only uses cold hammer forging for everything from rimfire rifles, through pistols, Scorpions to Brens.

Your incorrect. The actions are casted, I broke a few in half by accident. That's how I know. Saw casting voids and could not successfully tig weld without using a lot of gas The finish is parkerized some have been melonite coated.

[@nathan00campbell]

I fell for the CZ rimfire hype. Ended up getting a very nice bull barreled thumb hole stocked CZ 457. It was chambered for 22 long rifle and had one huge problem. The first shot of the day would always be about 5 in away from point of aim at 50 yards. Randomly anywhere. After that it would group dime size groups until you let the rifle sit for a few hours. Sitting for one solid hour didn't do it. Something about the rifle being in the AC would make the first shot wild. And I wanted it for varmint hunting so this pretty much made the rifle useless. Sent it to CZ three different times with no help. They claim they couldn't repeat the problem. Which is funny cuz it didn't care what ammo you put in it it had the same problem for the first shot of the day every single time. I didn't want to rifle that I had to walk out fire around off and then hopefully trust it when I finally see something to shoot at after the fact. Sold the rifle at a loss, and picked up a base model 457 that did the same damn thing. Returned it for my money back and have not bothered with CZ since.

[@crtxdistortion657]

Croissant wrench!😊

[@vektormaskin]

Sir, I’m sorry to tell you are wrong about the receiver beeing a cast item. It is definitely machined, either from bar stock or from precision tubing. Also, the CZ barrels are hammer forged, not button rifled. Threaded connections are inheritely less rigid than shrink fit or clamp fit. It works good for 22’s because of minor forces during the shot, so barrel is less likely to shift. Shrink or clamp fit might injure accuracy on 22’s due to slim tenons, short chamber and soft bullets, but are stiffer and better than threaded connections on larger calibers in the appropriate actions. Improvement point in your solution would be to incorporate a very tight cylindrical slip fit both ends of the thread. A lot less shift in barrel pointing is thus allowed. Yes, you have room for it. A 22lr need no more than 2 rev of fine threads.

What is the rough cost of all this work ? Wonder if it would be worth it for a rifle you just use for club matches?

[@garymeyer3294]

On average, how long does it take to do all the machining on the action and barrel?

[@tomallen6073]

Paid $450 for mine and going to accept it for what it is and leave it stock. Chasing infinitely smaller groups is like chasing the wind.

You don't know what you don't know or have expirenced.

@tomallen. I'm kinda with you on this. I have 3 different .22lr's that do 3 shot groups at 50 yards+ with all 3 holes touching. Can't think of a reason to mess with that. I guess if I was competing with guys who make 1 hole every time with 3 shots I might think about it. Also any gun is limited to the what the shooter can do. Bells and whistles do not equal skill. With that said, the knowledge and machining skills the guy has in this video are quite impressive.

I would have to agree it’s like Jimi Hendrix says “have you experienced?” “ Are you experienced?”

To this date 137 years of this cartridge. No current record is held in small bore benchredt, ARA, IBI ect. With a factory setup including Anchutz. Yes I can build a 22lr to shoot 1 hole 3 shot groups. I have built benchrest dedicated rifles that have shot records of 250-18x
