Gun Shells - Need help with IDing them

There is a small very old (ca 1880's) park near my house. I hunt it regularly and have found some nice items there. Currently there is a construction project going on right now at this park where they tore up some walking paths and scraped about 12 of dirt off of an area about 40' x 75'. The dirt is all piled up just waiting to be spread out again. I hunted the walking path trench and found a 1937 Buffalo nickel. I hunted the area where they scraped down 12 and found these shells. Please help me ID their approx age, thank you!

I found a bunch of shells (although they were shorter versions) with the letters U, P, H, and US. They were at a place that was started in 1894. I always figured they were turn of the century. I found a lot of them and they have to come from a time when you were allowed to hunt with the general public around. I'd say they date from the same time as your park.

yes they are from a rim fire gun most likely pre 1900 for sure

dang things ring in too solid in my opinion.

Some folks on another forum helped ID these as a .22 extra long which was first introduced in 1880, and the larger one is a Winchester .44 caliber Henry rimfire, first introduced in the 1860's. I am really excited to have found these and am waiting for them to spread out more dirt at this construction site where these were found.

Thanks for the update Milco.

Good luck when you get to detect there again!!
