This is actually going to be 2 questions.

I have a Remington 700 adl in .308 caliber. I bought a Nikon 3x9x40 scope and I' m not sure which scope rings to get. Which ones are going to hold up the best? I dont want to readjust my scope every 50-100 rounds because the scope has become loose in the rings. Whats your suggestions.

Next, whats the best way to sight this thing in? I have done it a few years ago with a 30-06 and shot 50 yards about an inch high so it would be good out to 200 or so. I haven' t hunted with a scope in several years and I want to be able to reach out to 200-300 yards. I will be shooting 150 grain ballistic silver tips. Please help.
