I have two things for mounting scopes that most people don't consider that makes it a much better job.
First, is powdered rosin that I use inside the scope rings to prevent slippage, even with magnums. Second is a special torque screwdriver especially made for mounting scopes, along with a pamphlet recommending torque used for various gun/scope screws. Over the years, I've had guns come in with broken-off base screws, and deformed scope tubes...from over-tightening . It's good to have a torque screwdriver to assure screws have adequate torque without damaging either screws or mount parts. Powdered rosin gives high gripping power to rings without threat of permanent adhesion. There's no reason to damage a scope or rifle just to make sure the scope won't slip. Red Locktite on base screws will assure that screws won't loosen. I also place a few drops under bases to prevent shifting under heavy recoil or fallen rifles.
It's also important to not lean scoped rifles against a wall, where they can get knocked down by either kids or rambunctious dogs. That happened to my son early one hunting morning. He went out of the room, looking for something and his dog knocked it to the floor. He didn't think he'd placed it there, but thought nothing of it, picked it up and was quickly out the door to go down back.
On his stool, placed in the woods access road a few minutes later, a nice buck came out about a hundred yards down the hill. He took careful aim and fired, but didn't hit it. Four shots later he still didn't hit it. It came back into the road from the opposite side and reloaded, he fired once more and missed.
Then, he looked at the scope and noticed that the objective was quite crooked, pushed downward toward the barrel.
A few minutes later, he was at my door with his rifle. I replaced the scope with my spare and we sighted it in and he was back in business.
After having his scope lying on the table in my shop for a while, I tried straightening it by laying it on my bench pad and "strategically" whacking it with my rubber mallet. It looked pretty good, so I mounted it on another rifle and gave it a whirl.
Everything worked fine and there were no creases, dents, etc. so it still resides on my rifle and my son still has the other scope, which is even better than the one bent by the dog.
