RB chamberings in Sharps cartridges

Does anyone know if the Remington RB's were ever chambered in Sharps company cartridges? Or did Remington use them and just change the designation of the cartridge? Any idea of caliber markings on the bottom barrel flat ahead of the forearm?

I have a RB chambered in 40-70 bottle neck. Book says it's the same as Sharps.  

Marked   40 70

Ballards may be weaker,
but they sure are neater!

The .44-77 SBN was originally not a Sharps exclusive cartridge, and originally marked .44-77 Remington-Sharps Bottleneck. 
Remington had a version of the .40-50 Sharps Straight, but called theirs .40-45 Remington Straight. Then UMC began loading it with 50 grains of powder and it became the same cartridge as the Sharps .40-50 Straight.
Remington was probably chambering their rifles for a lot more calibers by others than Winchester, or Marlin did. They didn't seem to have any qualms about it like the others did.

Roy Marcot's book on the Rolling Block lists the standard barrel markings, pages 76 and 77.

Some Remington caliber markings on their barrels can be somewhat confusing, as they used the same marking for different cartridge chamberings. Like using the same marking for the .44-77SBN, and the .44 Long at one point. 
But some are very specific, and only apply to one cartridge. Like their ".32-40 B&M" which is the standard .32-40 Ballard and Marlin we know today as simply .32-40.
Remington also changed the way they marked certain calibers over time. So there could be more than one marking for the same cartridge.

I always wondered how they kept them straight back in the day with all the different and changing cartridge designations.  Remington Hepburns and rollers to me would be the hardest along with Ballards  So many .44 catridges with just 44 or 44s on the barrel or  .32 or .32 B.  A lot of people were illiterate back then and I wonder how many swapped a mule for a gun and then wondered what he had or maybe walking into a hardware store back in Miles City and saying "I got this gun and need some catridges for it.  Whatcha got that might fit"?

I've always wondered why the early JM Marlin Ballard rifles never had a caliber stamped on their barrels? Later after Marlin incorporated and became Marlin Firearms Co. they stamped the caliber. 
Always thought it was so confusing to guess what caliber a Ballard is, back then or today. And especially so with all the .40 and .44 variations they were offered in!
And I wondered how many guys walked into a store wanting .40-63 Everlasting cartridges, and walked out empty handed because the store clerk didn't know his .40-70 cartridges fit the same gun? Or any of the other Everlasting cases too! Even after they marked the barrels, it was often marked for the Everlasting cartridge, so owners wouldn't always know the standard cartridge designation.

See, Vall, that's how they add 10 years to your life - trying to figure out what they are chambered for!

Thanks once again to the crew here for providing their insights. Very happy to see that it is possible to have a sporting type roller in 40-50ss, but that's another topic....

I have two in .40-50SS. One an original half octagon straight grip, and the other a built gun I did on an old military action, but using Remington stocks and a Remington pistol grip lower tang.

Haven't tried them at 1000 yds. yet, but have had very good accuracy out to 500 yds. with a 350 gr. bullet.

They look great, nice job on your build up! I believe that my roller in 44rf will be headed in the direction of this conversion. I'm just trying to find out which twist rate for the barrel liner that's available out there. Thanks for your posts, always appreciated!

I'd say 18 twist for any bullet weight up to 370 grains at up to 500 meters and 16 for heavier and/or farther.

The .40-50SS I built is a 1:16" twist. The factory original is a 1:18" if I recall correctly.
