Yep. .243 Winchester. I've never gotten anything while hunting with one. It's the cartridge I'd really love to switch to but its so unlucky for me. Two different hunting seasons I swore off all other chamberings and devoted entirely to the .243 and I didn't fill a single tag. I carried the cartridge a couple times last year but not as much as I would've liked to but I just feel unlucky with it. On the other hand the .30-30 and .30-06 have been my luckiest cartridges.
