Years ago, some bright guy that wanted to see people enjoy their 5mm rifles, engineered a way to put those rifles back to work. He worked the bolt to take a centerfire firing pin, and supplied shells for people to load their own cartridges. I never pursued it, so I am wondering how that all worked out. Any of your folks know? Any of you have one of those?

(searching this forum, I could find nothing pertaining to this.)

Gentlemen: Thanks!

I appreciate your information. Can't recall where I first heard of this conversion, might have been online, but I'm thinking it was a magazine. What a great story of a man having a dream and making it real. American ingenuity.
In one of the links shown above, from a varmint hunting forum, 2005, a poster who did the conversion wrote this:

"Maybe I'm an eternal optimist, but if someone ever markets 5MM RF ammo again, all I have to do is swap back to the RF bolt head and I'm back in business."

I hope the writer is still around to enjoy the wealth of 5mm rimfire ammo now available.

Thanks again.

There were Two individuals making the conversions--One was modifying the original bolt and the other furnished a complete bolt.

I have the Craig with the Xtra bolt it makes a nice cartridge especially now that we have different bullet weights to shoot

If you were looking to convert to centerfire James Calhoon sells detailed plans for the conversion

If you look at the specs of the 5mm Craig its not a big deal compaired to the modern loadings of the 22 Mag. Initially it was supose to do 21-2200 FPS but I doubt it did. Remington was trying to commercialize on the metric craze. They had the .244 failure that was renamed the 6 mm Rem. The excellent 7 mm Rem mag. Later the super 8 mm Rem mag. Then the another ecellent moderated 7mm-08. The 5mm just really didn,t deliver that much over the ,22 Mag. Like I said I dumped mine for the .223 waht ammo was close in price. Now I have a couple 22 mags, 22 Hornet, .223 and .243. So I,m over covered in that area. Just a neat cartridge that didn,t do anything better.

I have to disagree...

I have a 22WMR, a few 17HMR's and several 5MM's. All of them shoot well enough, but the devastation of the 5MM on critters far exceeds the other two. I choose my A17 as my go-to for sage rats just for the shear joy of a semiauto and cheaper ammo, but the 5MM is more fun to shoot them with. :)

So I.m thinking its the bullet construction? The velocity is very close and a couple thousands of an inch either way isn't a big deal. Or the 5mm Rem may fal into the MAGIC round like the .270 Win.

KE or bullet design I suppose. I have had multiple times where I shoot a sage rat and only find a tail and maybe a paw and/or head. Pretty much vaporized.

I have Hunted and shot the 5 MM since it was 1st introduced and now as bac then the 22 Mag the Nay Sayers did not then or NOW have any idea how the 5 MM FAR exceeds the 22 Mag

When it was 1st introduced Red Fox Hides were bringing anywhere between $ 125-200.00 for PRIME pelts.

There were four of us that called Fox on a regular basis 2 22 Mags 1 Hornet and my lonely 5MM during the 1st year we killed over 250 Fox Mostly Red and some Gray .

The Hornet was too destructive on the hides and the 22 Mag had a lot of hits and not confirmed --my 5MM NEVER failed to anchor a Fox and my Kill that years was 87 .

Before next season EVERYONE shot the 5MM

This discussion could go on 4ever BUTTTT until U actually see the difference U will not understand

RimfireFun, I have some older information on the 5mm conversion if your interested. First a two page reprint article from Guns Magazine from 4-24-2006. Second a reprint article by Jesse's Hunting & Outdoors about the conversion from 8-2-2007. And finally a price list from Quality Cartridge out of MD. giving prices for the conversion bolt head, reloading dies, brass, bullets, ect.. This from 8-2-2007 so none of it's current but you might find it interesting. If you'd like this information PM me an address and I'll mail it to you.

Sooooo why didn't become the the next super round instead of a dead round in 10 years? Guess it didn,t impress enough shooters. I love odd ball rounds and I owned it. But nothing special to me. I get it worked for you in your situation but most didn't see it that way.

I'd have to see proof of that, in that time frame Winchester was in financial trouble and Remington was flourishing. Plus the Remington rifles were a much better gun. The cartridge just failed to gain interest.

Because Winchester pumped 100's of thousands into advertising the 22MAG and Remington 10's of 1000's. They bought the market IMHO
Nah. I think it was several reasons. Having American rounds in the MM designation was new. THe 7MM Mag was just catching on. Then you had the .244/6MM screw up leaving shooters thinking whats, what? The .280 Rem should have out performed the .270 Win and 30-06 but wasn't close to either. Then the 5MM comes out. Some bought it like I did and within 10 years the cost almost tripled for a unreloadable round. Good Bye, hello cheap .223. Now we have all the internet to sing the praises of anything. Back then you bought what worked for people you knew or the gun mags praised.

5 mm centerfire conversion

Still have my 5mm I bought when they first came out and it is a tack driver.
I bought a second rifle way back and converted it to the 5mm Craig. The brass was like tin foil and easy to wrinkle when loading. Never got it to perform as well as the factory Remington ammo.I sold the centerfire converted rifle along with the dies, brass and heads long ago. Aguilla ammo doesn't perform as well but it keeps the caliber alive.

Well, I'm still reloading the little 5mm. Here's a post I made on the topic in the 5mm Forums just yesterday:

I have a couple of 5mm Remingtons with Schroeder centerfire bolt heads that two of my grandsons are interested in. The boys are nine and ten years old and like rifle and pistol shooting and all things related. I thought these would be a good start in their learning the art of handloading. One rifle is a 591, and the other a 592.

So yesterday I dusted off my 5mm RCBS dies and me and the boys loaded 100 rounds, each of them getting a 50-round box. The loads were comprised of 6 grains LilGun powder with either a 33-grain Hornady Vmax or a 36-grain Berger HP bullet, and Remington small pistol primers.

The brass is also from Schroeder, which is made from 22 Hornet cases. These cases have performed quite well for me during the 15 years I've been shooting them. I've got one group of 50 cases that I've reloaded 15 times so far, and none of the cases show any sign of problems. The only brass losses through the years have been a couple from neck-wrinkling from improper bullet insertion while being careless in reloading. Although the cases look a bit rough from the outside due to the conversion process using a lathe, they have proven to perform exceptionally well for me.

The overall length (OAL) of my handloads are designed to put the bullet real close to the rifling when chambered so there is little to no gap to jump, which can enhance accuracy. I'm careful to make sure they aren't long enough to jam in the rifling, because to do so usually means a stuck bullet and spilled powder in the action if they are withdrawn unfired. BTDT.

My handloads are about 1.48 inches OAL, compared to the rimfire factory OAL of 1.28 inches. The longer handloads with their aerodynamic long-nose bullets do not work through the magazines, but this is of no concern since I want to save the brass anyway. Forcefully ejecting the fired brass can cause it to disappear in the wild, so I am careful to extract them slowly and carefully to prevent that. I just hate to lose brass that can be reloaded many more times.

These 5mm rifles can achieve minute-of-angle accuracy at 100 yards with the right loads if the wind is not blowing and a proper bench rest technique is employed. They also do great on coyotes and crows out to 125 yards or so. With very little recoil, I believe the boys will be happy shooting these little gems.

The velocity from my handloads are around 2100fps, which is what I was looking for in order to approximate the velocity of the original 5mm rimfire cartridges from Remington. I could stuff a bit more powder into the case and get a few more fps, and indeed some folks have, but I find better accuracy not pushing for that last bit of speed. To me, accuracy is more important. And my cases last just about forever.
