Greetings all, on another forum there is a discussion of the relative effectiveness of the capabilities of the 458 WM on DG. Most maintain that the smallest effective 458 is the Lott, a very good cartridge but I think that the WM with a proper load (i.e. handload) is also effective. Say a 450/480 gr. at 2200 fps, others maintain that no it won't be as effective as the Lott, is 20 grs of weight and 100-150 fps really that imperative? The vaunted 450 Nitro was a 480 at 2150 correct? And it was well respected, whats changed? Have the big nasties gotten bigger and meaner? It's just a little confusing that one cartridge at a similar velocity/energy is effective while another would not be.

Experienced opinions?
