timberelk,
Your setup is good. In fact, I wouldn't have changed it from the first pic you sent. If I can get a dollar bill to slide between the objective lens and barrel, it's good. I like what MosesTheTank said about comfort and position. This, for me, is first on the list. I want to be able to put my cheek to the stock and the scope be aligned perfectly and not have to crank or stretch my neck to get a perfect, full field of view. The rifle should "fit" like a good boot. You put it on and it just fits, you don't have to keep adjusting it all day, they don't hurt your feet, and you're not "grabbing" them with your toes (like flip-flops). That's the way a rifle should come up, cheek "welded" to the same position every time, ready to do its business. If you have to crank your head and neck forward, it's not a good fit.
I don't think you will have any problems with the scope and barrel contacting during shots. I've had scope/barrel's closer and never had trouble. Good luck and let us know how she shoots! JohnnyK.
