Home Forums Hunting & Shooting BPCR The 8mm Danish roller - chamber is cavernous

so you know - it blew up BEFORE I did the strikers.

Shooting fine since. Still need to finish up the quarter rib and regulate it.



As for the ROB - Sell it?

Pshhhh

All this needs is a rebarrel, extractor, and bushing the firing pin from this 0.102" diameter one, correct?

Plenty of walnut here to put new furniture on.

Personally that looks like a typical Funnel type lead that was common back then. I don't think I would do a thing with it till you shoot it using proper bullets in it. Every BPCR rifle I have has that type of throat except one and they shoot quite well.
The photo below has a throat similar except it's not a bottle necked case but the lead is close and it will hold it's own for accuracy.

It's got roughly a 10 or 11 twist. And I have a 215 gr mould for it. Wish I would have bought a longer bullet though. Even short seated, the ogive will never meet the start of the rifling let alone where the diameter gets close to proper.

Funnel indeed.

I'll give it every opportunity before I quit .

Throwing a hotdog down a hallway... so to speak.

You have to get the 21st century shooting mentality out of your head and step back into the 19'h century when you shoot a 19'th century rifle.

Can you hook me up with some 19th century brass?

A lot of it.

Oh I don't know as I'ld go that far, it's not that much difference from the darling of the midrange and schuetzen boy's. 32-40..
Rebarrel to a 38-56 wincheter would be good with that Badger barrel, at least wouldn't have to screw with making a new extractor.

With all due respect, the 8 X 56 RD is, and was designed as a smokeless cartridge, and the pressure curve there is going to be hard put to provide the "bullet bump / slug up" that sorta' throating calls out.

At this point BP is WELL worth trying, and it would be no big deal to equip that rifle with a wiping rod, for field cleaning.

That is what I would try before doing something drastic. Also get a custom bullet mould that fits the throat.
I have shot some very long funnel throated rifles that shoot better then the modern 45 degree chamber ends.
Just look at the .22 rim fire chambers that range from a one degree to a three degree funnel throat. They have been used since their birth and are still used. They are a lead bullet lead.
But it's your rifle and you must be comfortable loading for it for your satisfaction but again that throat will shoot if you spend a little time working with it. you can always change it later on. Or sell me the rifle I don't much favor a roller even though I have had several and I don't have a girly caliber so it would still fit in for my use.

Case full of Olde Eynsford 1.5, compressed about .2, a thin felt wad and a greaser lubed with BSC lube, the cleaning rod can stay at home until the day is over...

Don. Don't forget a rn bullet for that throat

Worth trying, indeed,....

I want to SEE what a freebore called out by the print posted as being a whopping .0275" over the nominal greaser size required (or that one would normally start with is going to actually do ,.....prior to getting too overly enthused.

Greg,

With everything put aside when you can get a rifle with the long tapered throat to shoot like these targets using black powder I cant say the old throats used in the past wont shoot well. This .44-100 Rem has a fairly steep funnel lead of 5 degree compound taper into a 1.5 degree on the lands, 5 degree/1.5 degree compound. Granted these where shot at close range with only three shots working up loads but I see many modern rifles shoot a lot worse at this range.
My rifles have compound leads starting at 3 degrees to 5 degrees and they all shoot well.

Kurt,...I'm at a complete LOSS as to WTH we're supposed to be "putting aside" here.

I'm in complete AGREEMENT about tapered throats and compound leades,shooting like blue poison in BPCRs (you should take a long look at the chamber DWGs that Dave Kiff and I have noodled out over the years) I AGREE that loading ammo for RWE's Swede using the by-laws and codes associated with the theorum is the ticket.

I also KNOW that that thing was BORN to shoot a 210 gr (or thereabouts) Cupro Nickle jacketed slug. There WAS RUMORED to be a period during work up and initial "Conversions" that Christiana and the Steyr works WERE loaded with PP slugs,....and maybe that's what He's got here.

The .0275 Bump,than squishing down to a .323" Bore AIN"T gonna happen with any smokeless powder that I know of ( or would use). The original layout was about building the thing to shoot smokeless,....it's 'morphed".

Good input is good input,....and .0275" is and will remain a DIMENSION.

Smokeless with gilded jackets are a different game that needs back pleasure. No doubt about that.
Hey, y'all have a Happy New Year.
Kids are coming in the morning and my Daughter wants to shoot so I better get down in the mole den and throw some together for her to shoot.

Anybody looked at the dimensions of the 308 Marlin express cartridge to see if it would work for form the 8x58rd? I believe it's based off the 376 steyr, and Hornady makes cases for it and the 308 ME.. Might be something to think about if we're going to see a rash of these Dane rollers again..
