I've been waiting on this gun to come in for a long time, my first gun. I'll post pictures soon. I've been reading up a lot all around on forums and sites as much as i can find. But because I'm overly cautious about things like this so I could use some info to fill in the holes.

Gun= Savage 10FCP McMillan stock. Harris Bi pod. (still working on scope S&B or Leupold)

Bolt Lubricant.
What kind, and how to?

Ammo.
Will it hurt if i use 150g ammo instead of the the optimal 165-178g?
What is keyholing?

Muzzle Break
Set up do I have to do prep work (Barrel threading) for it, or just buy and it comes with instructions.

So far that's the only questions I have. Ill post pics as soon as I can.
