Just goes to show a little knowledge can be dangerous

The plastic scoop is a powder measure and it measures the same way that factory ammunition is loaded by "VOLUME" not weight.
Sorry I did miss the scales off the list as you might need them to perfect your "Dipping" technique. One you have done so your charge weights will vary very little.
There is nothing dangerous about the Lee Classic Loader unless a total idiot uses it incorrectly. Same can be said of the most expensive "O" frame press.
Now the Lee Loader has been in use for over half a century quite safely too. Unless your a real clutz or a ham fisted moron then there will be not problems. They even made a target model which not only neck sizes but also reams the neck in the die so it's the same thickness of neck all round but also perfectly aligned. The hand loaded rounds produced with a Lee Loader if a bullet, powder and primer that your rifles likes is used will shoot very well indeed. The handicap is usually the "nut behind the Butt"
There are several people on these forums that use the Lee Loaders.
