T/C bedding
 

I have T/C Renegades and Hawkens that I have thought about bedding but am a little confused about where to bed. I know that some will bed the tang and triggers but where would you bed the barrel? I have done center fire rifles before with good results just doing the recoil lug to just in front of the action. Any suggestions? Do I do the whole barrel channel or just the action area and the end of the stock?

Normally right by the wedge key. Tang/screws also get it when I do them.
