The Danish RB rifle that most people see is the 67/96. These were all Danish made and were the only rifles adapted to the new smokeless cartridge Denmark adopted in 1896. All of the 67/96 rifles received a new rear sight and the new cartridge was slightly longer than the original rimfire cartridge.
Generally speaking, all Danish-made rifles were converted to the smokeless, centerfire round and all Remington-made rifles were not...

There are two blackpowder-only versions, the...

OK, here is a small portion of a letter sent by Freund Brothers to Sharps Rifle company dated May 9, 1877 from Cheyenne Wyoming.
Remington does not make a 40-90 for two reasons, 1st is thier breech will not stand the charge. The next sentance really spells it out. It may be interesting perhaps to give you a little history of an accident that occured to a man at Red Canyon, Wyo. last fall while using the .40 calibre gun of Remington make. The gun had been re-chambered by someone in...

I have been reading Ballantines book on the Fruend brothers and found some interesting information. Remington did not keep records on failures, most gun manufactures did not becuase of the liability issue. Tonight I will try my hand at typing out the exact writting in the book, but the short of it is a 45-70 was rechambered to 45-90 this is way back in the 1800's and it was in a news paper article Fruend referanced. It said that the shooter died as the breech block went thru his skull....

Two of my Egyptian Rollers have very striated receivers. To the point that it look like rings in a twisted cross section of wood. I've never run across such recievers in any other model. Almost like the metal was already cooling when the reciever was cast. I don't believe I would shoot either of those.

Well Herb my old friend, carbine loads are for girls ! Real men and certifiable nuts like me have health insurance for shoulder reconstruction.

My Swede does have a slight golden tint to the frame but I think this is just patina, definately not case hardening. I used to have a sporter made from the early Remington ordered Swedes, the comparison between the two was quite stunning. The frame of the Swedish built carbine is like a Remington on steroids, much more massively built although the innards appear to be the same in terms of scale.

I think you're right, Richard. The steel ( or iron, more likely) is very "grainy". Almost a grey iron. At Bendix we smelted scrap steel with grey iron sprues and runners for disc brake calipers and fractures looked exactly the same. I brought up the case-hardening thing because the pre-failure photo seems to have a cased receiver. I know that some muzzle-loaders used to artificially case-color lockplates and triggerguards with cold blue and tincture of benzoin (I think...

Richard, there may be something wrong with the photograph in your last post. It does not show on my screen.

I can't imagine an owner polishing off case hardening and I can't imagine there being much sign of case hardening left on your typical well used 135+ year old rifle. Neither of my Danes show any sign of case hardening and if they were polished it was a long, long, long time ago. What my frames are is the silver-grey appearance I'd expect on 135 year old receivers that haven't been refinished. The crystalline structure evident in the pics of the failure point to a pretty...

Crikey! What kind of flame thrower do you have in your Avatar Paul? They must be rifle loads you're using.

Not seen a Danish one fail before, but have seen the remains of a Swedish one and a US one. Pattern of failure appears to be consistent: no sign of fatigue (cumulative damage) cracks. Catastrophic failure of barrel and breach due pressures way over the norm. Rolling block breach mechanism held. I have seen a photograph of one other failure which did appear to have a possible fatigue crack in the breach--the whole thing was pretty rusty so it was not possible to be sure.
The guy who had a...

Seems to be an unusual number of reports of these Danish rifles breaking. One post I saw on another other board says this may be associated with the steel used on the gun and the conversion of the guns from rimfire to centerfire.

As I go through the boards this morning, I'll watch for that post and link it here.

Bullet stuck in bore? Air in cartridge over black powder? Load seems mild enough. WOW! Thank the powers--that-be that the shooter got out of it in as good condition as he did!
I shoot a Dane RB!! Anyone see a failure like this before? Given the Worlds Fair trials with umpteen bullets and a handful of powder........
