I bought the Lee Classic Powder Measure (LCPM) and like using it. I get consistent, accurate weights such as others have reported.
Using the Reduced Load Calculator and the directions provided with the LCPM I developed loads for my 7mm-08 and my 338 Federal. The 7mm is a Ruger Hawkeye and the 338 is a Savage Model 11.
The two moulds for which the the loads were developed are the Lyman 150 grain round nose, gas check; and the Lee 220 grain. Both give good accuracy in their respective rifles. My alloy is WW. I double with Ben's Liquid Lube. Each round is calculated for 1800, 1900 and 2000 fps.
The directions provided with the measure recommend that their figures are estimates only and that one should develop their own data using the powder they have, rather than rely on their data. Even doing that, I found that I still had to find tune the specific CC setting for each load. I did not include the VMD as that will vary slightly with your powder.
The powders used are those recommended by the Lyman Cast Bullet which I had on hand.
Here is the data I developed, 7mm first. I hope you find this helpful.
Do your homework, double check my figures and compare with a reliable manual, such as Lymans. I typically shoot in the 1800 to 1900 fps range. And I note for example that my top load for 4198 is higher than the top load recommended by Lymans. I double checked all of my calculations. Nevertheless,Exercise caution
