I think people generalize elk hunting to much in the constant elk caliber, cartridge, bullet threads.

What I would find acceptable for watching a saddle or trail may not be acceptable when slipping through a North slope looking for a bedded bull. I have no problem shooting, or having a kid use a 243 with a good bullet on the earlier but would not do it on the later.

The Village idiot from Oregon will be along shortly, but I have never been able to see a difference on animals between the likes of a 308, 270,30-06 etc. Maybe somebody that has been around more kills than me has, but I haven't seen it.
