I had the same issues with a new 700ADL that I had put a cheap Bushnell scope on with see through mounts. The gun sat in my closet for a long time because I didn't care to shoot it. I eneded up changing the scope to a Nikon with Warne rings and mounts and that made a huge difference. With some other minor fine tuning, I'm getting 1/2 to 1 1/2 inch groups now. I'm keeping it! I think your scope is probably the issue and would start there.
