However, my go to book is always #### Lee's Modern Relaoding. In your case, it may be the best one for you to start with, since there is a section on the Lee Loader. You will also find references to its use in both 3 and 4 of Dean Grennel's ABC's of Reloading. I probably read each and every one of these books every two years or so. Just to bring things to mind. EXCEPT The Cast Handbook. Still haven't gotten into that yet, but it is coming soon. Just need a mold that will give me a 215gn .316" bullet for my 1898 Lee Enfield Carbine. Then I will no longer be able to resist.
