@Bob Nelson 35 Whelen, got me to thinking about the vast utility of the .35 Whelen (I own 3 and want another, but that's another story).
So, I ran some numbers (we all know this is just math, but relatable) comparing the .35 Whelen to the .338 Win Mag, 225 grain bullets, MV used in calculation.
Calculations are from Gregor Woods excellent book, "Rifles for Africa" printed in 2002.
His term is Relative Damage Potential, (RDP) upgraded from Taylor's KO values. Again, this is just a mathematical factor, used for comparison among various cartridges.
It does not include real world factors like shot placement, bullet construction, terminal bullet ballistics, specific animal physiology, moon phase, etc.
Mr. Woods updated John Taylors "Knock Out" values (African Rifles and Cartridges, 1948) to capture, the cross-sectional area of various bullets, as well, as bullet weight and velocity as John Taylor did. The basic formula for RDP (Relative Damage Potential) is:
Bullet Weight x Velocity x Cross-sectional Area

7000
Examples are:
.30-06 RDP 5.2
.375 H&H RDP 11.9
.458 WM RDP 23.9
Results for .35 Whelen vs. 338 Win Mag: (225 grain bullets, MV from Speer #14 reloading manual)
.338 Win Mag RDP 8.2
.35 Whelen RDP 8.6
So, @Bob Nelson 35Whelen, is on point.
The .35 Whelen delivers .338 Win Mag performance, and more, with 20% less powder and (in my experience) 20% less recoil.
