Gents:
I have an 1872 new York contract rolling block Remington in .50-70. Can the chamber be lengthened to .50-90 or even 50-100-450"
Cal

Cal, some longer chamberings won't work because the cases hang up on the hammer. Also, that NY contract rolling block may have enough collector value that altering it wouldn't make sense.

Another couple of comments: The twist in that barrel is likely to be very slow, and the groove diameter may well be on the large side for modern .50 bullets. Also, case length of 50-90 Sharps is 2.5", case length of 50-100-450 Winchester is 2.4".

One other thing - I had an unmodified 1868 Springfield 50-70 of the same vintage and the chamber basically had no definite end, unlike modern chambers. It just had a very gradual taper inside from cartridge case mouth diameter into the lands some distance away. Mine would accept a case 2-1/4" long (shortened 50-90 brass) with a seated 450 grain bullet and actually shot quite well that way (with BP of course). I have no idea at all whether the Remington might have a similar set up, but it's worth checking.

The answer is NO. If you do, the hammer will need to be notched, and you will likely have a step in the chamber and brass.
Leave it alone.

"I have no idea at all whether the Remington might have a similar set up, but it's worth checking."

Swedish Remington rolling blocks was an early rimfire 12,7*42r they were made to be made from model 1860 muzzleloaders the 1860 model Wrede use a .480 hollow base which swell under pressure. They can also be used with a tighter bullet but it must be cleaned often. As remade to a breach loader the 1860-1867rb use a .500-.505 bullet ~438gr.

The rolling block actions were later made in to model 1889 8mm*58r with a harder locking block and new block pins made to take the pressure from compressed BP loads. These rifles are a better fit for a custom rifle and they are only about 250$ a modified Husky for hunting maybe 50$.

Nordic, I have two of those re-arsenaled Model 67/89 rolling blocks, one barreled to .50-70 and one soon to be barrelled to .44-77. Both barrels from Green Mountain.
The two donor rifles had already been sportered, and in 8X58. Triggers are crisp but still quite heavy. I just ordered the spring kits from Kenn Womack at RollingBlockParts.com. The guys on the ASSRA forum say the simple trigger return spring change-out makes a significant difference in pull.
Cal, these 67/89 sporters are pretty affordable at Simpson Ltd. and are an excellent choice for building a rolling block to your taste.

I just swapped out the trigger return springs with the Kenn Womack wire springs, and good grief what a difference!

I just saw a 12,7*44r/.505 Carl Gustaf 1867 hunting model with what seems like a 1889 block and full stock (mannlicher) at auction valued 160$.

I would like to have one as the 12,7*44r are not accepted as a hunting caliber here.

Nordic: Sorry to hear the 12,7x44 is not allowed for big game hunting anymore. Its near twin, the .50-70, was very widely effectively used on bison here in North America.
God Jul to you and yours, sir.
