Guys-
Have been thinking of stuff to do for winter projects and have been thinking of bedding one of my M70 featherweights. I've been through Dave's detailed post (which was great, BTW) and I still have some general questions that I know people here can answer.

1. I know bedding is to make a rifle more accurate, but what is the actual, technical reason it makes a rifle more accurate?

2. I see in Dave's post the areas that he bedded (recoil lug, tang, barrel chamber)...are those the only areas to which one would apply bedding?

3. I noticed he "honed out" the barrel channel in the stock...why is this done? I assume its because the barrel is being "free floated", but isn't it that way from the factory already?

4. This may be a really stupid question, but why isn't the entire length of where the barrel contacts the stock bedded? (i.e. Why is the barrel "free floated") What is the technical reason for this?

Pardon my ignorance and thanks in advance for replies
