Customer Reviews

Arnie from Palm Bay, FL writes: Hi..I'm a long-time user of Lee products. I recently bought the new Auto Drum powder thrower and wanted to tell how how slick it works...Some of the rifle powders are so very fine, like sand, they would give my trusty old Lee Perfect Powder Measure fits...wanted to gum it up all the time, no matter how I set the tension....Took a chance on the new Auto Drum and it handles the extremely fine powders perfectly!......I use the Classic Cast single stage, but have the Auto Drum set up on your inexpensive Reloader Press......I could not be happier....Keep up the great work.....(.As an aside, after trying all your case trimming tools...my old Zip Trim is still the fastest and still the easiest to use..love it)

Lee, I'm a fan. I rarely write in on products, but wanted to on yours.
I was considering a turret press, and had looked at the Lee. I talked to a reloading shop and told them I was looking at the Lee, and they suggested the Lyman. I started looking at different sites, and reading different reviews, and decided to go with the Lee Classic 4 Hole Turret. I had purchased Lee Deluxe Die Set also. I also researched powder dispensers, and bought a Lyman 55. After I received the turret and the dispenser, I tried to figure out how to connect the Lyman 55 to the Lee die, even contacting your support. I read where people epoxied and taped and other rigging methods. I decided to return the Lyman 55 and order the Lee Auto-Drum Powder Measure, and I am very happy. The Auto-Drum is so consistent. I set it up and a couple of days later went back and measured it, and it was spot on! I have gone to only checking every 50th round as it is so accurate and so consistent. I will wholeheartedly recommend the Lee Classic Turret, the Lee Deluxe Dies and the Lee Auto-Drum Powder Measure.
