If all you hunt is whitetails and hogs then the 140 gr Core-lokts is all you need if they group well. Medium sized game doesn't require premium bullets. I know a PH in Africa that has a Ruger #1 in 7x57 as an extra rifle for clients whose rifles go down or just want to try it. He loads it with 150 gr Hornadys. I used it on an impala once and they seemed to work well.
