I was told by a gunsmith not to do that because eventually I would screw up (bend or break) the extractor. The last part of this paragraph pretty well says the same thing. Since that discussion with the gunsmith I strictly load into the magazine with the number it's designed to hold and then load the top one into the gun the way it's designed for the extractor to grab and hold it. Here is the paragraph from an article on the difference between a push feed and controlled feed system that says the same thing the gunsmith told me in the last couple sentences:

In controlled feed bolt actions, called “Mauser type” actions in some instances, the base of the cartridge slips up and under the extractor from a magazine, and is held against the bolt face during insertion into the chamber. These extractors are also known as “claw” extractors and are relatively large – easily identified by the flat bar that runs along the outside of the bolt. This extractor sits in a groove along the action, and stays stationary as the bolt rotates. Because of its design, the cartridge base sits flush against the bolt face, but is not as fully supported at the chamber mouth as the push feed design. While it may be possible to chamber a round without first inserting it into the magazine, it is not reliable and can cause damage to the rifle or cartridge. It should be noted that Winchester has recently developed a “controlled round push feed” bolt action in specific calibers that can be fed individual rounds reliably.
