Ten Pointer
I totally agree with bryguy and others about using good, solid mounts for any optics. However a cheap scope mounted solidly to a hard kicking rifle may be lucky to last long enough to be properly zeroed. Several times I've seen people with brand new setups (like a nice $900 rifle and $175 scope)- they get it on paper at 50 yards, back up to 100 and halfway through a group the entire erector system inside the scope lets loose (and this is on a .270 or 30-06, not a 300 or larger bore rifle). All of my rifles currently wear DZ, Leupold or Kimber bases and rings and I've never had a minute's trouble with any scope coming loose.
