For the first prototype, I decided that a single shot rifle would be perfect to start with. That would allow me to have a rifle in hand that I could test, before tackling any magazine/feeding issues and possibly halting the project all-together. Besides, my new favorite rifle was my Thompson Contender Carbine, so having a single-shot was actually preferable to me.
After trading my daughter an IPhone for her CZ Scout (in .22 Long Rifle caliber), I had the gun delivered to my gunsmith. He proceeded to work his magic, even after running into a few issues that were unforeseen. I had ordered a barrel blank in .204 caliber from Green Mountain Rifle Barrels and had him chamber, cut, contour (the best he could) and fit the barrel. Of course he did his best to redo the short Scout stock, so it would fit an adult shooter. My fears of this becoming a "Franken-Rifle" became realized when I opened the box after receiving it. I chuckled to myself when I first picked it up, because it was one ugly rifle. But, the question soon became, how would it shoot?
For my first outing, I mounted a Center Point Mildot scope I had recently acquired, with some BKL Medium rings. The fit was good, the rifle felt comfortable and if I closed my eyes, I could actually imagine it being a factory CZ Model 452 in the 5mm Remington Rimfire Magnum caliber!
I took it up to the Central Valley area of Southern California and proceeded to sight it in. I had no problems dialing it in and proceeded to shoot three shot groups with the Centurion Ammunition (both White Box and Varmint), as well as with the original Remington 38 grain offering. The results were good at 75 yards (top) and a second trip at 100 yards (bottom):
I have some hunt reports that I will be putting up in the next few days. The results are as to be expected with any 5mm Rimfire... Devastating!!
Lastly, I wanted to explain why I put this up right now. I know the folks who love this caliber are getting very discouraged with the way things are going with regards to new rifles. I wanted to put this out there to let you know that I am working on some alternatives that should fill the need for now. I don't recommend everyone run out and pick-up one of these CZs and hand it off to just any gunsmith to convert. Although this is a working prototype, there is still a lot of work to have a final version that I can say works safely and flawlessly, we are VERY close!!
Hang in there and keep checking back here for more information on this project! Also, feel free to link this story any where you want.

No extraction issues either (I just hit 400 rounds through the gun).
Btw, the only reason I am not getting into details is because I do not want people to think it is a simple switch, so they run to their gunsmith and create a hazardous rifle. There were internals changed as well.
Glass - I am working with another couple of gunsmiths on this and we are taking a completely different route than Lowell.
Here's a teaser from one of my hunts:

a new suitable action to handle a cartridge that was way ahead of its time.I think with all the new powders and bullet technology we have now,the time is ripe for new life with the 5mm.

Just curious, what were the problems with using a Ruger 77/22 action, especially one originally chambered for the .22 Magnum?

Also will be interesting with the new WSM and how it will perform compared to the 5mm Mag because as of today the most powerful hard hitting round out there (I believe) is the 5mm Mag with the 30 grain JHP varmint bullet at a MV of 2300 fps with 352 ft. lbs. of muzzle energy.

17's just don't appeal to me. To fast, to light, and not enough oomph behind it. Like shooting a needle through a rabbit.

I'll get the entire story and video up next week.
