Lead bullet with one groove and cartridge with no headstamp found, old?

[Eero]

Found a lead bullet and a cartridge without headstamp, both found a couple inches deep.
I have found an 1880s shotgun shell in the same area, but I have no idea if these are old...

I believe the cartridge is a rimmed .303 cartridge.

Since nobody else has spoken up to help ID your finds, I'll give it a try. I concur with your belief... a (very early) rimmed .303 cartridge... could be a British .303, an early Winchester .303, or early Savage .303.

In particular, I note that it has an "extraction flange" but lacks an extraction-groove above the flange. This excludes it from being a .30-06 Springfield cartridge.

The bullet appears to be a late-1800s .44 revolver bullet. Definitely later than civil war era because the patina shows it is made of a hardened-lead alloy rather than pure-lead.

Thanks for the information. Everything I learned about old cartridges, and where I found them, is consistent with them being old, but I couldn't say definitively.
I appreciate the help.
