I've been using the Lee scale now for ten years. If you take the time to learn to use it you'll find it's one of the most accurate scales on the market for a beam scale. I've had several other scales from RCBS and Lyman and have yet to find one that will come close to the accuracy of the little Lee.
If your looking at the Modern Reloading Manual by Richard Lee, that's the one that comes with the Anniversery kit it has both starting loads and maximum loads (never exceed loads) listed. I'm not sure what came with your kit. The loads that Lee lists are actually loads from the Hodgen manual.
I've been loading for 45 years now and have used most of the equipment out there. There is some excellent equipment on the market and most all of it makes excellent reloads. Only thing I can say about getting a better scale is go the Lyman or RCBS or PACT electronic scale/dispenser. Thats the only system I've found that even comes close to the Lee scale.
I sure do recommend gettin as many manuals as you can. Also check out online manuals. Many powder companies have load manuals on line that are basically free.
Here's my bench setup. You will notice I put my scale up at eye level where it's easy to see. Any balance beam scale will benifit from this kind of positioning.
One of the tests of an accurate scale is how low a measurement it will make. Lee's can measure the weight of a pencil mark on a small piece of paper. The test is in Lees reloading book. Try that with any other balance beam scale.
Bottom line is there's lots of good equipment on the market, lord knows I've bought plenty of it. I'm particular about how well my guns shoot and spent a few years chasing the benchrest thing along with lots of years shooting one sort of NRA competition or another.
The Lee equipment though much complained about by some delivers excellent accuate loaded ammo along with being a "best buy" in reloading equipment. Their factory service has been excellent for me and though the little scale does not resemble some of the others on the market once you learn to use it you may find it a very good accurate scale.
Sometimes the most expensive is not really the best.
