.50-70 Remington Trapdoor 1884 manuf.

Looking for bullets for a 1884 mauf. Rem trapdoor in .50-70. All my research says .515 bullets but my uncle, the owner of the gun says .512 is what the seller told him.

Does anyone reload for the above rifle? What bullet diameter are you using? Any resources you can point me too? Plan is too use 70 FF.

Thanks for the help.

Do you mean a Rolling block?
I've got a modern C Sharps, and have owned an 1868 and 1870 Trapdoors.
Both shot .512 decently.

By 1884, I think all the trapdoors would be 45-70. But trapdoor or rolling block, the current "standard" bullet for a 50-70 is 0.512. That's what I load in mine, unless I'm running a 0.504 paper patch. Both seem to work well. You could slug the bore in yours - it could vary in those old guns. One note on paper patched bullets. Since you are not seating to a crimp groove, you can leave a little more space for powder. I can fit 70 grains of holy black under one of those. For a standard bullet, not quite, more like 65. And I use 1 1/2Fg, more consistent.

They make an outstanding bullet.

Remington didn't make Trapdoor rifles... Those were Springfields.

As others have noted, the .50-70 Trapdoor was out of production by 1873, when the .45-70 cartridge replaced the .50-70.

I'm not even sure that the US Navy Rolling Blocks, which were ordered in the early 1870s, were made past 1875. And I'm pretty sure all of those were chambered for the carbine cartridge, not the full rifle cartridge.

As far as I know, standard bullet diameter was always .515. That's not to say that your barrel isn't either tighter or looser.

I read the 50-70 was finally withdrawn from active service in 1881.
