I killed my first deer a long time ago with a Winchester post 64 featherweight 257 Roberts and a Speer 120 grain Hot Core over an appropriate charge of IMR 4350. I ended up taking several deer with that combination before I moved on to other rounds. I have an FN Mauser in 257 now. I've not hunted it much but still love the round. I load 120 Partitions now but think it would be hard to fault any of the available 117-120 grain bullets for deer with a 257 Roberts.
