As long as we're talking commie calibers, I've taken several deer, including one large buck (~140 pts B&C) with my CZ 527 in 7.62x39. It killed them all DRT, but on two of the larger deer it failed to make exit wounds, so I've discontinued the practice, except for small does. If 7.62x39 is marginally adequate, the Mosin should excel in my estimation.
