Actually for efficiency...I'd go a .25 Souper.
See John's article (old) on efficient cartridges.
In my opinion....
.257 Weatherby is way overbore and a waste of good powder.
.25-06 is better, but still a bit of a waste.
.257 Roberts...sweet.
.25 Souper, efficient.
.250-300, Classic
25 Remington, 25-35 etc. Beautiful......
Maybe (any of the above) even built on a #1 with a 26" barrel.
All of that with the understanding that I don't shoot at game animals over 300 yards away. I'm just not as good a marksman as some other folks I know.
