I've had this discussion many times with folks. I generally argue that smaller cartridges should not be recommended generally for the following reasons:

1) Most hunters shoot their guns about two times a year. One confirmation shot and one shot on the first deer that walks out in front of them.

and

2) Most hunters get buck/doe fever and can't place the perfect shot on a deer. (I've spent time at the processor and have look at the deer and seen the entry and exit holes, scary!)

Larger more powerful bullets typically allow for more margin in error.

Also I wish folks would get off the 300 WM shooters are the worst etc... etc... While I have to agree there seems to be a slight trend I chose the 300WM for it's ballistics and managabel recoil, not to mention the versitility of game it can take easily. I can shoot mine just fine.
