Possibly the best 160gr. for all heavy game could be the Barnes TS. At 2,640fps, my 7x57 BRNO put them into 5/8" at 100 meters. It is possible the 7x57 might not drive this bullet fast enough for it to be as an effective bullet as a slightly softer one, like the Partition or Hot Core. I haven't shot anything with it.
: My second choice for all-round would be a 160 to 175gr. Partition. Even a Speer Hot Core 160gr. would probably hold up well, if only driven at 2,600fps, an easy going, low pressure load for modern rifles.
