Ranch13 nice elk nice rifle. Two Saturdays ago I helped my neighbor slaughter a 1200# Holstein steer for burger meat he killed it with a 22short from 6" but I wouldn't hunt elk with it. I've killed moose with a 243 so I don't doubt you could kill elk with your .405 doing it well. Dead is dead it is like asking about bullet failure after cutting it out of the carcass, just where did it fail.
Jorge: lions and tigers have thin skin and they're plenty dangerous for me! I've never killed either my experience with DG has been limited to a a few brown bears in NA and cape buffalo in Africa for the bears I used a 30-06, 338WM & 45-70 the latter a .458WM with a 450 gr TSX ( no I didn't shoot them @ 1000)
