There's options to keep an 348 running. It's been mentioned that swaging down 35 cal bullets can work. Casting 348 bullets survey can work. Another real possibility would be to paper patch 338 250gr roundnose bullets. If paper patching 338 work that would be amazing and make all those boutique hard to find bullets obsolete. I'd wager the 338 bullet is pretty tough at 348 win velocities.
