I also think neck sizing is ok for hunting. Chambering every round is a good idea. Has anyone ever heard of someone getting a round stuck from dirt because of not FL resizing? I mean if you have that much dirt in the chamber I think it would stick one that has been FL sized also.
The only thing I can think of that would be a problem is if your chamber was out of round to begin with. If the concentricity of the fired case body is good, there shouldn't be any problem.
Having said that, if you had a slight run out on the case body, that would probably be taken care of by FL resizing. I have a rifle that has .004 runout at the base of the chamber that makes it oval. Even FL resizing will not get it to chamber, but if you rotate it to the right position, it will drop in.
