I haven’t hunted anything with a 375win, but I did just have a 94 Big Bore in 375 come into my shop for repair. New in Box, never fired, and needs to stay that way - but during normal fondling, the owner realized it won’t eject. Looks like the extractor is seized, so it won’t be too tough to fix, but still have to find a few rounds to use as dummies. Gorgeous rifle though, and seems like it would be a fantastic thumper.
