I would agree that if you shoot an elk with a small caliber 243 up to a 458Wm and the bullet gets both lungs and critically damages the cardiopulmonary system, the elk is down and out.

I have seen elk go a long way on others with a marginal shot hitting one lung.It is these shots that would benefit from a bigger caliber, That is why I think 243's and elk are a poor combo. Everything must go perfect with the smaller calibers.At longer ranges past 200 yds I want 30 cal and larger penetrating expanding bullets.

I would luv to have a Double round with the ballistics noted(200gr at 2800) for longer range shooting of deer, bear,elk,et al,but it is what it is.

Zimhunter-
Fascinating. I wonder if a Double would handle the 8x60mag round.
