A few years ago I arrived in a hunting camp where the PH’s were discussing the success of the prior hunter. He was maybe 12 and was a little guy. His dad was very experienced and let the young man do all the shooting. He used a 260 with 120 grain bullets. The rifle had a 20” barrel and his dad mentioned that he didn’t load too hot to minimize recoil. Anyhow the kid dropped everything with a single shot. His bag included the general run of plains game except eland.
The group that preceded him consisted of two guys packing, respectively, a 300 Win and a 338 Win. They didn’t do as well.
There you go.
