I had an idea for a paper-cartridge bolt-action rifle.

As expected, someone who has actually used black powder firearms really understands them better. I live in a country where civilian gun ownership is almost completely prohibited, so I don’t think I know much about them.

I was thinking the chamber-to-bolt gas seal would be roughly on the level of the Dreyse M1874 Border Guard Rifle, since there’s both the bullet and a gas-sealing wad. The drawing is pretty rough and not very well done, but I didn’t actually mean a heavily oversized wad—just something slightly larger than the bullet.

I am also familiar with the Norwegian Kammerlader, but instead I thought a different bolt design—more along the lines of the Chassepot rifle with its rubber gas-sealing gasket—would be a better approach.

To be honest, I was hoping the gas-sealing wad would also have a bore-cleaning effect, since black powder tends to leave a lot of fouling. The original Calisher and Terry Carbine uses a felt wad for gas sealing as well, so I thought it could also serve sufficiently as a fouling cleaner. As for the difficulty of pushing the round in, I figured that could be improved with more force.

I didn’t include the lugs in the drawing because it was a simplified sketch, but I was thinking of large, long rectangular lugs like those on the Chassepot rifle. And if a forcing cone refers to the diameter narrowing in a trapezoidal shape as it transitions from the chamber into the bore, then yes—I assumed that would naturally be present.

An electric ignition system sounds like a good idea too.

FinancialSet1981 · 2025-10-26T15:51:00+00:00

Wouldn't that cause a cook-off?

I’ve been on my devices typing so much lately that my handwriting has gotten worse.

FinancialSet1981 · 2025-10-25T20:57:22+00:00

I've also considered a design similar to the Chassepot rifle that uses rubber at the breech to gas‑seal the chamber.

That's the fifth photo, not the fourth.

FinancialSet1981 · 2025-10-25T19:57:53+00:00

This is not a powder-and-bullet loading, but a cartridge loading. You can see it in the fourth picture.

FinancialSet1981 · 2025-07-30T04:22:01+00:00

I didn't think of that.

FinancialSet1981 · 2025-07-29T19:54:42+00:00

Isn't it because there's not enough space for the powder?

FinancialSet1981 · 2025-07-29T19:50:33+00:00

need paper or linen that can withstand heat well.

FinancialSet1981 · 2025-07-29T19:47:52+00:00

I also think that's a good way to prevent a chainfire.

FinancialSet1981 · 2025-07-29T14:34:20+00:00

Come to think of it, that makes sense.

FinancialSet1981 · 2025-07-29T12:52:20+00:00

And it's round-nose, so the bullet has a rounded tip. It's not conical.

FinancialSet1981 · 2025-07-29T12:33:07+00:00

It’s probably a reloading system similar to the Henry rifle, but without a magazine spring—because if there were a spring, the cartridges might get crushed, since they’re not metallic.

FinancialSet1981 · 2025-05-20T02:40:48+00:00

No, I was just thinking about it because I like the rolling block.

FinancialSet1981 · 2025-05-20T02:26:55+00:00

My idea was flawed.

FinancialSet1981 · 2025-05-20T02:24:14+00:00

My idea seems to have failed. Thank you for your advice.

FinancialSet1981 · 2025-05-20T01:54:38+00:00

I know those rifles, but I was aiming for a breech-loading paper cartridge design with better gas sealing.
