Grandfather's Mauser. Had it made up with a left-handed stock. I had to take it to a gun shop to figure out what round it took; everything I could find online/ChatGPT pointed to 6.5 Swedish but I wasn't quite sure as my mother thought it was chambered in 30.06 which would be uncommon but still I wanted to make sure. Gun shop confirmed 6.5 Swedish so I bought a few boxes and ended up getting to shoot it on a property I'm working at currently. Shoots great, smooth action, scope is pretty far out of whack so I need to work on that but still it was super fun getting to shoot this old hunting rifle that my grandfather really liked. I suspect the conversion was done sometime in the 50s or 60s.
