ok, have taken my share, of the calibers I have used, which are, 223, 22-250, 6mm ppc, 243, 243 win., 6mm, 6.5 creed, 6.5 Gibbs, 25 wssm, 270, 7mm/08, 280, 7mm mag, 7mm stw, 7mm Allen Mag., 30 herret, 30-30, 308, 7.62x39, 348 win., 350 rem mag, 375 JDJ, and 458 socom. from the 243 to the 7mag I see zero difference. those rounds approaching 3500 fps mv do stand out. but for an average deer hunter, you won't see a difference, prove me wrong!
