Ok guys, since I am a novice- let's talk about basic rear bag shooting technique. This is part 2 of my questions, I figure if we can get the experts here to answer, these would be really good threads for newbs such as myself when they search for technique data. 
What do we want to do? How well/tightly should the rifle fit in the bag? What kind of adjustment/front rest do you use and why? What brands are worth having? How heavy should the rest be? Any other tips and tricks?
Thanks!
