Actual kills.....30-06 (165 gr. Horady Interlock), .338 Mag. (250 Gr. Swift A-Frame), .338 Mag. (Federal High Energy wit 250 Gr. Woodliegh).
AS to the "flinch" argument that is so popular with those who are trying to justify why they use smaller calibers....It's been my experience that those who are really good shots, can shoot anything well.
Note, I did NOT say they "enjoy" shooting the big boomers as much. Nobody actually "likes" getting pounded (particularly in long sessions at the bench), but a "good" shooter is still good with whatever he shoots.
Those I see who preach the "flinch" argument, in general, tend to flinch with every rifle they shoot (including the .22 LR at times). A poorly disiplined shooter doesn't get any better no matter how small a round he choses. Flinch is just a convienient excuse.
Some mat see it differently, but that's what I've observed.
