I don't see the need in this case, or calibre as it were. The 7X57 is blessed with good bullets from the get go.

As much as I like premium bullets, the 7m/m already has heavy bullets with good sectional densities, good hunting velocities along with adequate case capacity, and the power to do the job. I'm mot saying no, just implying that here is a good place to save money.

If we were talking about thr .270 I'd argue the other direction. I've loaded a truckload of 130's, and at close range they do leave gaping holes.
