In my current inventory? Hmmm. Maybe the 7.5X54 French. It's a 308 WIN-ish kind of chambering, but it only fits in a MAS 36.
I'd give an honorable mention to 44 Mag at least as a rifle round. Again, I'm not throwing shade on the chambering. It did a really good job on a whitetail this season. Still, it's not going to be delivering the kind of versatility as the 45-70, and it isn't a good varminter.
