do components (dies,cases molds) exist for the 12.1744r cartridge? Also is this a center fire? I have a chance to buy a swedish rolling block in beautiful condition.

It's the Swedish version of the 50-70 with a minor twist. You have to take the rim diameter down to fit and that's about it. I don't have a lathe so I end up just chucking it in the drill press and hitting with a file. It obviously doesn't take a lot to get them ready. 50-70 bullets work fine and I also like a .500 minie with a paper patch. My only warning is some of the versions of rollers have smaller buttstocks and can feel like a pretty hefty kick. Mine is the muzzle loader conversion with the larger buttstock and is nicer to shoot. But they are fun and well built so give it a try.

One more thing. Some of the early ones are rimfire and the later ones are often center fire so be sure to check it or be prepared to switch out the breechblock or do a conversion.

If it's the rimfire, I don't want it. Thanks, Lucky

Many later Danish rollers can switch from rimfire to centerfire like a Contender. Many also were converted to 45-70 in the States for the surplus market. I have one of these.

Good point in the Danish rollers. (Now I want a snack) Mine is weirdly chambered so it is more like a 45-80 the way it's throated. But that is a good way to recycle any mangled 45-90s too. Antique foreign rifles are sometimes extra interesting.

44R means 44 Rim Fire.

No personal experience, but these rifles are fairly common here in Scandinavia. They were the standard military rifle in Norway and Sweden, and were sold to civilians after their service. The military used rimfire cartridges, but most rifles were converted to centerfire when sold to the civilian market.

.50 Alaskan brass is popular here, it only requires shortening a little. You can also convert .348win cases.

Die-sets are available from RCBS and CH4D, but they are not cheap. Many use 50/70 gov't die sets, and it usually works.

Dedicated moulds were made by a mould maker in Sweden ("Jämttången"), but these are scarce and expensive even hereabouts. Many use moulds designed for 50/70 and size down.

Mashburn: The add I was looking at was confusing in the wording and stated the rifle was both centerfire and rimfire. That's why I got this thread going. The rifle I'm now looking at is centerfire and very similar to the 50-70.

The R means rimmed in the European parlance; not rimfire. Think 7.62x54R.

Thanks for the 50 Alaskan info. I just got some from Starline but haven't had a chance to try them out.

I believe I have the same one you have looked at. I use the Lee hollow based mold. It drops at about .460”. I shortened 45-90 brass to fit my chamber. I use about 75g of ff. It’s a pretty good shooter. The sights are pretty good.

Delmarskid: I've told that the 50-70 is very close, not a .45.?

Hello Lucky 1

Thanks for catching my goof up on rimfire and rimmed cartridge. I definitely know the R following cartridge caliber stamping means rimmed case. How I made that error is beyond me. Not only is the error a big surprise,but  that I caught the mistake, edited it and evidently typed in rimfire instead of rimmed the second time.

I either had my head in my anterior posterior region, or I may need to be in a CRS care center. Seriously, I have been working on two rimfire firearms for the last two or three weeks and I guess my brain is pre-occupied with rimfires Being 81 years old doesn't help much either. Thanks for letting me know, I can't believe that I did this.

I think I have a late made one. An early one may be closer to a .50”.

I did a quick scan of this and it looked helpful.

Hopefully I can clear this up a hair. We actually have a discussion going about 2 different Scandinavian rollers. Swede at 50 and Danish at 45 caliber. Both are admittedly cool in their own right. Yes, I do have the 45 HB Lee and also a .500 minie from Lee for the Swede. 45 in Danish goes out at cast and the .500 gets paper patched for the Swede.

Thanks for the memory jolt. I have the Danish roller.

Delmarskid- finally got a look at the article you posted. Thanks because it does give another perspective on the process. We all get focused on some things at certain times and I admit to having problems shifting gears too. There's still a lot less chaff over here to sift through.

I read your article too. It raises a question: is the 12.7x44R the same as the 12.17 by 44R? I've seen both used in reference to the same rifle.

Not a cartridge collector, but they appear to be referring to the same thing. The difference seems to be Swedes and Germans did it one way and Norwegians did it their way. Similar to 7.62x54R with the Russians and 53R with the Finns.
